  • Batch resize images (overwriting)

    Requires ImageMagick to be installed; mogrify is the lesser-known sibling to convert -- it overwrites your original images, but allows you to work on batches of files without resorting to a loop.

  • Command to rename multiple file in one go

    An entirely shell-based solution (should work on any bourne-style shell), more portable on relying on the rename command, the exact nature of which varies from distro to distro.

  • Delete all empty lines from a file with vim

    Here's the other way of doing it in vim: setting a recursive macro. 'gg' brings you to the top of the buffer, 'qqq' clears the 'q' macro, 'qq' starts recording a macro called 'q', '/^$' moves the cursor to the next empty line, 'dd' deletes the line that the cursor is on, '@q' calls the 'q' macro (currently empty because of 'qqq'), and 'q' stops recording the macro. '@q' calls the macro. It will run until it cannot find another blank line, at which point it will throw up an error and cease. While this is longer than the regex, you can use it without having to move your thoughts from 'vim-mode' to 'regex-mode'.

Exclude inserting a table from a sql import
Starting with a large MySQL dump file (*.sql) remove any lines that have inserts for the specified table. Sometimes one or two tables are very large and uneeded, eg. log tables. To exclude multiple tables you can get fancy with sed, or just run the command again on subsequently generated files.

find duplicate messages in a Maildir
# find assumes email files start with a number 1-9 # sed joins the lines starting with " " to the previous line # gawk print the received and from lines # sort according to the second field (received+from) # uniq print the duplicated filename # a message is viewed as duplicate if it is received at the same time as another message, and from the same person. The command was intended to be run under cron. If run in a terminal, mutt can be used: mutt -e "push otD~=xq" -f $folder

Calculate md5 sums for every file in a directory tree

E-mail a traditional Berkeley mbox to another recipient as individual e-mails.

Swap a file or dir with quick resotre
This lets you replace a file or directory and quickly revert if something goes wrong. For example, the current version of a website's files are in public_html. Put a new version of the site in public_html~ and execute the command. The names are swapped. If anything goes wrong, execute it again (up arrow or !!).

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"

List all Windows services on the command line
On Windows 2000 or later, this command will give a listing of all the registered Windows services. You can then know what the name of a command is in order to start and stop it. e.g. $ sc start Apache2.2 or $ net start Apache2.2 Please note that sc will allow the SERVICE_NAME only, while net will allow both SERVICE_NAME and DISPLAY_NAME. Note that the space between the = and the next word are important. Not very unixy, that. http://www.ss64.com/nt/sc.html http://www.ss64.com/nt/net_service.html http://technet.microsoft.com/en-us/library/bb490995.aspx

Re-use the previous command output
The $(!!) will expand to the previous command output (by re-running the command), which becomes the parameter of the new command newcommand.
