diff two css files to create an overriding css (e.g. for wordpress child themes)

This will extract the differing CSS entries of two files. I've left the initial character (plus or space) in output to show the real differing line, remove the initial character to get a working CSS file. The output CSS file is usable by either adding it in a below the to original.css, or by only using the output but adding @import url("original.css"); in the beginning. This is very useful for converting Wordpress theme copies into real Wordpress child themes. Could exclude common lines within entries too, I guess, but that might not be worth the complexity.

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.

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Using parcellite, indents the content of the clipboard manager

This command takes the content of a Parcellite-managed clipboard manager and add one level of indentation to it. It may be useful to indent a block of code which will enter inside another, already indented one but I use it mostly to indent code I will post in Stack Overflow questions and answers.

A command to copy mysql tables from a remote host to current host via ssh.

This version compresses the data for transport.

Using commandoutput as a file descriptor

Description is moved to "Sample output" because the html sanitizer for commandlinefu breaks the examples..

Convert seconds to [DD:][HH:]MM:SS

Converts any number of seconds into days, hours, minutes and seconds. sec2dhms() { declare -i SS="$1" D=$(( SS / 86400 )) H=$(( SS % 86400 / 3600 )) M=$(( SS % 3600 / 60 )) S=$(( SS % 60 )) [ "$D" -gt 0 ] && echo -n "${D}:" [ "$H" -gt 0 ] && printf "%02g:" "$H" printf "%02g:%02g\n" "$M" "$S" }

Remote Serial connection redirected over network using SSH

Requires software found at: http://lpccomp.bc.ca/remserial/ Remote [A] (with physical serial port connected to device) $./remserial -d -p 23000 -s "115200 raw" /dev/ttyS0 & Local [B] (running the program that needs to connect to serial device) Create a SSH tunnel to the remote server: $ssh -N -L 23000:localhost:23000 user@hostwithphysicalserialport Use the locally tunnelled port to connect the local virtual serial port to the remote real physical port: $./remserial -d -r localhost -p 23000 -l /dev/remser1 /dev/ptmx & Example: Running minicom on machine B using serial /dev/remser1 will actually connect you to whatever device is plugged into machine A's serial port /dev/ttyS0.

Write comments to your history.

A null operation with the name 'comment', allowing comments to be written to HISTFILE. Prepending '#' to a command will *not* write the command to the history file, although it will be available for the current session, thus '#' is not useful for keeping track of comments past the current session.

list block devices

Shows all block devices in a tree with descruptions of what they are.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.
