Project description
The Atmark – Awk+sed for humans.
Do this:
# Rename file in current directory (file-name -> file_name.jpg) $ ls | @ replace - _ "mv # @.jpg" | sh
Except this:
# Rename file in current directory (file-name -> file_name.jpg) $ ls | awk '{print $1 $1}' | sed s/"-"/"_"/ | awk '{print "mv", $2, $1, ".jpg"}' | sh
More deep:
$ ls | @ replace - _ "mv # @.jpg" | sh ------- | | ------------ | | | \_ format string (# - link on first state, | | | @ - link on current state (after replace)) | | | | | \_ second replace param (to replace) | | | \_ first replace param (what replace) | \_ function name (replace)
More examples:
# Change files extension .html > .php # Atmark $ ls | @ split . head "mv # @.php" # Awk/Sed $ ls | awk '{printf "mv "$0; sub(/html/,"php"); print " "$0}' | sh # Print all but the first three columns # Atmark $ ls -la | @ split_ drop 3 join_ # Awk/Sed $ ls -la | awk '{for(i=1;i<4;i++) $i="";print}' # Kill process by name # Atmark $ ps aux | @ grep sysmond$ index 2 "kill @" | sh # Awk/Sed $ ps aux | grep [s]ysmond | awk '{print "kill "$2}' | sh
And more, more, more.

Usage
$ @ --help Atmark (@) -- is a command line utility for parsing text input and generating output. You can pipe data within a Atmark (@) statement using standard unix style pipes ("|"). Provide for Atmark function composition and let them work for you. Example. Replace "_" with "-" in files in current dir and change the files extensions to jpg: $ ls | @ replace _ - split . "mv # @.jpg" It is mean: $ ls > replace($LINE, "_", "-") > split($RESULT, ".") > format($RESULT, "mv $LINE $RESULT.jpg") You can use "@ --debug ARGS" for debug Armark commands. =================================================================================== LIST OF THE BUILT IN FUNCTIONS format PATTERN -- format and print a string. Symbol '#' in PATTERN represents the line of the input (before pipe "|"). Symbol '@' in PATTERN represents the current value in process of composition of fuctions. Synonyms: You can drop `format` function name. This lines are equalent: $ ls | @ upper format "@.BAK" $ ls | @ upper "@.BAK" capitalize/c -- capitalize the string. drop N -- drop N elements from list/string. filter/if -- filter results by value has length grep/g REGEXP -- filter results by REGEXP head/h -- extract the first element/character of a list/string index/ix/i N -- get the N-th element/character from list/string. join/j SEPARATOR -- concatenate a list/string with intervening occurrences of SEPARATOR join_/j_ -- same as join but SEPARATOR set as ' ' last -- get last element/character of incoming list/string. length/len -- return length of list/string. lower/l -- make the string is lowercase replace/r FROM TO -- replace in a string/list FROM to TO. reverse -- reverse list/string. rstrip/rs PATTERN -- return the string with trailing PATTERN removed. sort -- sort list/string. split/sp SEPARATOR -- return a list of the substrings of the string splited by SEPARATOR split_/sp_ -- same as split by splited a string by whitespace characters strip/s PATTERN -- return the string with leading and trailing PATTERN removed. tail/t -- extract the elements after the head of a list take N -- take N elements from list/string. upper/u -- make the string is uppercase
