All -e SCRIPTs are concatenated together as if separated\nby newlines, followed by all lines from -f SCRIPT_FILEs, in order.\nIf no -e or -f SCRIPTs are specified, the first argument is the SCRIPT.\n\nEach COMMAND may be preceded by an address which limits the command to\napply only to the specified line(s). Commands without an address apply to\nevery line. Addresses are of the form:\n\n [ADDRESS[,ADDRESS]][!]COMMAND\n\nThe ADDRESS may be a decimal line number (starting at 1), a /regular\nexpression/ within a pair of forward slashes, or the character \"$\" which\nmatches the last line of input. (In -s or -i mode this matches the last\nline of each file, otherwise just the last line of the last file.) A single\naddress matches one line, a pair of comma separated addresses match\neverything from the first address to the second address (inclusive). If\nboth addresses are regular expressions, more than one range of lines in\neach file can match. The second address can be +N to end N lines later.\n\nREGULAR EXPRESSIONS in sed are started and ended by the same character\n(traditionally / but anything except a backslash or a newline works).\nBackslashes may be used to escape the delimiter if it occurs in the\nregex, and for the usual printf escapes (\\abcefnrtv and octal, hex,\nand unicode). An empty regex repeats the previous one. ADDRESS regexes\n(above) require the first delimiter to be escaped with a backslash when\nit isn't a forward slash (to distinguish it from the COMMANDs below).\n\nSed mostly operates on individual lines one at a time. It reads each line,\nprocesses it, and either writes it to the output or discards it before\nreading the next line. Sed can remember one additional line in a separate\nbuffer (using the h, H, g, G, and x commands), and can read the next line\nof input early (using the n and N command), but other than that command\nscripts operate on individual lines of text.\n\nEach COMMAND starts with a single character. The following commands take\nno arguments:\n\n ! Run this command when the test _didn't_ match.\n\n { Start a new command block, continuing until a corresponding \"}\".\n Command blocks may nest. If the block has an address, commands within\n the block are only run for lines within the block's address range.\n\n } End command block (this command cannot have an address)\n\n d Delete this line and move on to the next one\n (ignores remaining COMMANDs)\n\n D Delete one line of input and restart command SCRIPT (same as \"d\"\n unless you've glued lines together with \"N\" or similar)\n\n g Get remembered line (overwriting current line)\n\n G Get remembered line (appending to current line)\n\n h Remember this line (overwriting remembered line)\n\n H Remember this line (appending to remembered line, if any)\n\n l Print line, escaping \\abfrtv (but not newline), octal escaping other\n nonprintable characters, wrapping lines to terminal width with a\n backslash, and appending $ to actual end of line.\n\n n Print default output and read next line, replacing current line\n (If no next line available, quit processing script)\n\n N Append next line of input to this line, separated by a newline\n (This advances the line counter for address matching and \"=\", if no\n next line available quit processing script without default output)\n\n p Print this line\n\n P Print this line up to first newline (from \"N\")\n\n q Quit (print default output, no more commands processed or lines read)\n\n x Exchange this line with remembered line (overwrite in both directions)\n\n = Print the current line number (followed by a newline)\n\nThe following commands (may) take an argument. The \"text\" arguments (to\nthe \"a\", \"b\", and \"c\" commands) may end with an unescaped \"\\\" to append\nthe next line (for which leading whitespace is not skipped), and also\ntreat \";\" as a literal character (use \"\\;\" instead).\n\n a [text] Append text to output before attempting to read next line\n\n b [label] Branch, jumps to :label (or with no label, to end of SCRIPT)\n\n c [text] Delete line, output text at end of matching address range\n (ignores remaining COMMANDs)\n\n i [text] Print text\n\n r [file] Append contents of file to output before attempting to read\n next line.\n\n s/S/R/F Search for regex S, replace matched text with R using flags F.\n The first character after the \"s\" (anything but newline or\n backslash) is the delimiter, escape with \\ to use normally.\n\n The replacement text may contain \"&\" to substitute the matched\n text (escape it with backslash for a literal &), or \\1 through\n \\9 to substitute a parenthetical subexpression in the regex.\n You can also use the normal backslash escapes such as \\n and\n a backslash at the end of the line appends the next line.\n\n The flags are:\n\n [0-9] A number, substitute only that occurrence of pattern\n g Global, substitute all occurrences of pattern\n i Ignore case when matching\n p Print the line if match was found and replaced\n w [file] Write (append) line to file if match replaced\n\n t [label] Test, jump to :label only if an \"s\" command found a match in\n this line since last test (replacing with same text counts)\n\n T [label] Test false, jump only if \"s\" hasn't found a match.\n\n w [file] Write (append) line to file\n\n y/old/new/ Change each character in 'old' to corresponding character\n in 'new' (with standard backslash escapes, delimiter can be\n any repeated character except \\ or \\n)\n\n : [label] Labeled target for jump commands\n\n # Comment, ignore rest of this line of SCRIPT\n\nDeviations from POSIX: allow extended regular expressions with -r,\nediting in place with -i, separate with -s, NUL-separated input with -z,\nprintf escapes in text, line continuations, semicolons after all commands,\n2-address anywhere an address is allowed, \"T\" command, multiline\ncontinuations for [abc], \\; to end [abc] argument before end of line." 482 483 #define HELP_rmdir "usage: rmdir [-p] [dirname...]\n\nRemove one or more directories.\n\n-p Remove path\n--ignore-fail-on-non-empty Ignore failures caused by non-empty directories" 484 485 #define HELP_rm "usage: rm [-fiRrv] FILE...\n\nRemove each argument from the filesystem.\n\n-f Force: remove without confirmation, no error if it doesn't exist\n-i Interactive: prompt for confirmation\n-rR Recursive: remove directory contents\n-v Verbose" 486 487 #define HELP_renice "usage: renice [-gpu] -n increment ID ..." 488 489 #define HELP_pwd "usage: pwd [-L|-P]\n\nPrint working (current) directory.\n\n-L Use shell's path from $PWD (when applicable)\n-P Print canonical absolute path" 490 491 #define HELP_pkill "usage: pkill [-fnovx] [-SIGNAL|-l SIGNAL] [PATTERN] [-G GID,] [-g PGRP,] [-P PPID,] [-s SID,] [-t TERM,] [-U UID,] [-u EUID,]\n\n-l Send SIGNAL (default SIGTERM)\n-V Verbose\n-f Check full command line for PATTERN\n-G Match real Group ID(s)\n-g Match Process Group(s) (0 is current user)\n-n Newest match only\n-o Oldest match only\n-P Match Parent Process ID(s)\n-s Match Session ID(s) (0 for current)\n-t Match Terminal(s)\n-U Match real User ID(s)\n-u Match effective User ID(s)\n-v Negate the match\n-x Match whole command (not substring)" 492 493 #define HELP_pgrep "usage: pgrep [-clfnovx] [-d DELIM] [-L SIGNAL] [PATTERN] [-G GID,] [-g PGRP,] [-P PPID,] [-s SID,] [-t TERM,] [-U UID,] [-u EUID,]\n\nSearch for process(es).
