Check a directory of PNG files for errors

Useful for checking if a large number of PNG files was downloaded successfully by verifying the built-in CRC checksum. For incomplete files, the command will print: "00002309.png EOF while reading IDAT data ERROR: 00002309.png" The process is very fast; checking 21,000 files of 5MB in size took only five minutes on a 2011 Intel mobile dual-core.

Extract all urls from the last firefox sessionstore.js file used.

Require "grep -P" ( pcre ). If you don't have grep -P, use that : grep -Eo '"url":"[^"]+' $(ls -t ~/.mozilla/firefox/*/sessionstore.js | sed q) | cut -d'"' -f4

Extract all urls from last firefox sessionstore used in a portable way.

If you want all the URLs from all the sessions, you can use : perl -lne 'print for /url":"\K[^"]+/g' ~/.mozilla/firefox/*/sessionstore.js Thanks to tybalt89 ( idea of the "for" statement ). For perl purists, there's JSON and File::Slurp modules, buts that's not installed by default.

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

List the size (in human readable form) of all sub folders from the current location

Sorted in human readable format.

Execute most recent command containing search string.

Execute the most recent command containing search string. This differs from !string as that only refers to the most recent command starting with search string.

Advanced python tracing

Trace python statement execution and syscalls invoked during that simultaneously

List all duplicate directories

Very quick! Based only on the content sizes and the character counts of filenames. If both numbers are equal then two (or more) directories seem to be most likely identical. if in doubt apply: $ diff -rq path_to_dir1 path_to_dir2 AWK function taken from here: http://stackoverflow.com/questions/2912224/find-duplicates-lines-based-on-some-delimited-fileds-on-line

processes per user counter

enumerates the number of processes for each user. ps BSD format is used here , for standard Unix format use : ps -eLf |awk '{$1} {++P[$1]} END {for(a in P) if (a !="UID") print a,P[a]}'

Re-emerge all ebuilds with missing files (Gentoo Linux)

Generate the CPU utilization report

Generated the CPU utilization stats with 5 lines /every 2 seconds. Needs sysstat package to be installed prior to use sar.

Scan for new SCSI devices

Issues a scan command on the given scsi host adapter (ex. a fibre channel adapter, in the example above on host0). Output can be watched in the messages log or in "dmesg"

one-liner mpc track changer using dmenu

Add a [fluxbox] binding in your key file then this command provides a dmenu selector for the next track to play

Convert CSV to JSON

Replace 'csv_file.csv' with your filename.
