Introduction

Here you will find a lot of small applications, you don't find on your desktop task bar. No starter is there but on your computer. You can use them only on the cli. All commands are connected to the man pages. So you can read how to use them.

Content

Directory Description
/usr/bin/addr2line The addr2line utility translates program addresses specified by the command line arguments hexaddress to their corresponding source file names and line numbers. If no arguments are given to addr2line, it will read these addresses from standard input.
/usr/bin/alias a shell built-in command The shell maintains a list of aliases which can be set, unset and printed by the alias and unalias commands. See [1]
/usr/bin/apply The apply utility runs the named command on each argument argument in turn.
/usr/bin/apropos The apropos and whatis utilities query manual page databases generated by makewhatis(8), evaluating expression for each file in each database. By default, they display the names, section numbers, and description lines of all matching manuals.
/usr/bin/ar The ar utility creates and maintains groups of files combined into an ar chive. Once an archive has been created, new files can be added to it, and existing files can be extracted, deleted or replaced.
/usr/bin/as AS the portable GNU assembler
/usr/bin/asa The asa utility reads files sequentially, mapping FORTRAN carriage-control characters to line-printer control sequences, and writes them to the standard output.
/usr/bin/asn1_compile The ASN.1 library contains routines to handle ASN.1 encoding for SNMP. It supports only the restricted form of ASN.1 as required by SNMP.
/usr/bin/at The at and batch utilities read commands from standard input or a specified file which are to be executed at a later time, using sh(1).

/usr/bin/atrm The at and batch utilities read commands from standard input or a specified file which are to be executed at a later time, using sh(1).
/usr/bin/awk awk scans each input file for lines that match any of a set of patterns specified literally in prog or in one or more files specified as -f progfile. With each pattern there can be an associated action that will be performed when a line of a file matches the pattern.
/usr/bin/b64decode [2] The uuencode and uudecode utilities are used to transmit binary files over transmission mediums that do not support other than simple ASCII data. The b64encode utility is synonymous with uuencode with the -m flag

specified. The b64decode utility is synonymous with uudecode with the -m flag specified.

/usr/bin/b64encode [3] The uuencode and uudecode utilities are used to transmit binary files over transmission mediums that do not support other than simple ASCII data. The b64encode utility is synonymous with uuencode with the -m flag specified. The b64decode utility is synonymous with uudecode with the -m flag specified.
/usr/bin/banner Banner prints a large, high quality banner on the standard output. If the message is omitted, it prompts for and reads one line of its standard input.
/usr/bin/basename basename, dirname return filename or directory portion of pathname
/usr/bin/batch The at and batch utilities read commands from standard input or a specified file which are to be executed at a later time, using sh(1).

/usr/bin/btsockstat The btsockstat utility symbolically displays the contents of various Bluetooth sockets related data structures. There are few output formats, depending on the options for the information presented. The btsockstat utility will print results to the standard output and error messages to the standard error.
/usr/bin/bunzip2 bzip2 compresses files using the Burrows-Wheeler block sorting text compression algorithm, and Huffman coding. Compression is generally considerably better than that achieved by more conventional LZ77/LZ78-based compressors, and approaches the performance of the PPM family of statistical compressors.
/usr/bin/byacc Yacc reads the grammar specification in the file filename and generates an LALR(1) parser for it. The parsers consist of a set of LALR(1) parsing tables and a driver routine written in the C programming language. Yacc normally writes the parse tables and the driver routine to the file y.tab.c.

/usr/bin/cksum The cksum utility writes to the standard output three whitespace sepa rated fields for each input file. These fields are a checksum CRC, the

total number of octets in the file and the file name. If no file name is specified, the standard input is used and no file name is written.

/usr/bin/clear tput, clear -- terminal capability interface
/usr/bin/cmp The cmp utility compares two files of any type and writes the results to the standard output. By default, cmp is silent if the files are the same; if they differ, the byte and line number at which the first difference occurred is reported.
/usr/bin/col The col utility filters out reverse (and half reverse) line feeds so that the output is in the correct order with only forward and half forward line feeds, and replaces white-space characters with tabs where possible. This can be useful in processing the output of nroff(1) and tbl(1).

/usr/bin/crunchgen A crunched binary is a program made up of many other programs linked together into a single executable. The crunched binary main() function determines which component program to run by the contents of argv[0]. The main reason to crunch programs together is for fitting as many programs as possible onto an installation or system recovery floppy.
/usr/bin/crunchide The crunchide utility hides the global symbols of object-file such that they are ignored by subsequent runs of the linker, ld(1). Some symbols may be left visible via the -k keep-symbol and -f keep-list-file options. The keep-list-file must contain a list of symbols to keep visible, one symbol per line. The names given by keep-symbol or in keep-list-file should be C names. For example, to keep the C function "foo" visible, the option "-k foo" should be used.
/usr/bin/crypt The enigma utility, also known as crypt is a very simple encryption program, working on a "secret-key" basis. It operates as a filter, i.e., it encrypts or decrypts a stream of data from standard input, and writes the result to standard output. Since its operation is fully symmetrical, feeding the encrypted data stream again through the engine (using the same secret key) will decrypt it.
/usr/bin/csplit The csplit utility splits file into pieces using the patterns args.
/usr/bin/ctags The ctags utility makes a tags file for ex(1) from the specified C, Pascal, Fortran, yacc(1), lex(1) and Lisp sources. A tags file gives the locations of specified objects in a group of files.
/usr/bin/ctfconvert The ctfconvert utility converts debug information from a binary file to CTF data and replaces the debug section of that file with a CTF section called SUNW_ctf.

/usr/bin/cut The cut utility cuts out selected portions of each line (as specified by list) from each file and writes them to the standard output. If no file arguments are specified, or a file argument is a single dash (`-'), cut reads from the standard input. The items specified by list can be in terms of column position or in terms of fields delimited by a special character. Column and field numbering start from 1.
/usr/bin/dc dc -- desk calculator
/usr/bin/dialog Dialog is a program that will let you to present a variety of questions or display messages using dialog boxes from a shell script.

/usr/bin/du The du utility displays the file system block usage for each file argument and for each directory in the file hierarchy rooted in each directory argument. If no file is specified, the block usage of the hierarchy rooted in the current directory is displayed.
/usr/bin/edit The command ee is a simple screen oriented text editor. It is always in text insertion mode unless there is a prompt at the bottom of the terminal, or a menu present (in a box in the middle of the terminal). The command ree is the same as ee, but restricted to editing the named file (no file operations, or shell escapes are allowed).
/usr/bin/ee The command ee is a simple screen oriented text editor. It is always in text insertion mode unless there is a prompt at the bottom of the terminal, or a menu present (in a box in the middle of the terminal). The command ree is the same as ee, but restricted to editing the named file (no file operations, or shell escapes are allowed).

/usr/bin/elfdump elfdump -- display information about ELF files
/usr/bin/enigma The enigma utility, also known as crypt is a very simple encryption program, working on a "secret-key" basis. It operates as a filter, i.e., it encrypts or decrypts a stream of data from standard input, and writes the result to standard output. Since its operation is fully symmetrical, feeding the encrypted data stream again through the engine (using the same secret key) will decrypt it.
/usr/bin/env The env utility executes another utility after modifying the environment as specified on the command line. Each name=value option specifies the setting of an environment variable, name, with a value of value. All such environment variables are set before the utility is executed.
/usr/bin/etdump etdump -- Dump El Torito boot catalog information from ISO images
/usr/bin/ex ex, vi, view -- text editors; vi is a screen-oriented text editor. ex is a line-oriented text editor. exand vi are different interfaces to the same program, and it is possible to switch back and forth during an edit session. view is the equivalent of using the -R (read-only) option of vi.

Its purpose is to retrieve the file(s) pointed to by the URL(s) on the command line.
/usr/bin/fg Shell builtin commands are commands that can be executed within the running shell's process. Note that, in the case of csh(1) builtin commands, the command is executed in a subshell if it occurs as any component of a pipeline except the last.
/usr/bin/fgrep grep, egrep, fgrep, zgrep, zegrep, zfgrep, bzgrep, bzegrep, bzfgrep - print lines matching a pattern
/usr/bin/file file tests each argument in an attempt to classify it. There are three sets of tests, performed in this order: filesystem tests, magic tests, and language tests. The first test that succeeds causes the file type to be printed.
/usr/bin/file2c The file2c utility reads a file from stdin and writes it to stdout, converting each byte to its decimal or hexadecimal representation on the fly. The byte values are separated by a comma. This also means that the last byte value is not followed by a comma. By default the byte values are printed in decimal, but when the -x option is given, the values will be printed in hexadecimal. When -s option is given, each line is printed with a leading tab and each comma is followed by a space except for the last one on the line.

/usr/bin/keylogin The keylogin utility prompts the user for their login password, and uses it to decrypt the user's secret key stored in the publickey(5) database. Once decrypted, the user's key is stored by the local key server process keyserv(8) to be used by any secure network services, such as NFS.
/usr/bin/keylogout The keylogout utility deletes the key stored by the key server process keyserv(8) to be used by any secure network services, such as NFS. Further access to the key is revoked, however current session keys may remain valid till they expire, or are refreshed. This option will cause any background jobs that need secure RPC services to fail, and any scheduled at jobs that need the key to fail. Also since only one copy is kept on a machine of the key, it is a bad idea to place this in your .logout file since it will affect other sessions on the same machine.
/usr/bin/kf kf -- securely forward tickets
/usr/bin/kgetcred kgetcred obtains a ticket for a service. Usually tickets for services are obtained automatically when needed but sometimes for some odd reason you want to obtain a particular ticket or of a special type.
/usr/bin/killall The killall utility kills processes selected by name, as opposed to the selection by PID as done by kill(1).
/usr/bin/kinit kinit -- acquire initial tickets

/usr/bin/lastcomm lastcomm -- show last commands executed
/usr/bin/leave leave -- remind you when you have to leave
/usr/bin/less Less is a program similar to more (1), but which allows backward move ment in the file as well as forward movement. Also, less does not have to read the entire input file before starting, so with large input files it starts up faster than text editors like vi (1).
/usr/bin/lessecho lessecho is a program that simply echos its arguments on standard output. But any metacharacter in the output is preceded by an "escape" character, which by default is a backslash.
