Renames all files in the current directory such that the new file contains no space characters.
This is a better version, as it does no command piping, uses for instead of while loops, which allows for a list of files in the current working directory to be natively processed. It also uses the -v/verbose option with mv to let you know what the command is doing. While the command does exactly the same in a better way, I would modify the sed option to replace spaces with underscores instead, or dashes. Please note that you'll receive errors with this command as it tries to rename files that don't even have spaces.

Change prompt to MS-DOS one (joke)
This one eliminates the additional backslash at the end (which is not necessary)

i want to count how many regex code i have used in vim in a long time so i make a directory in svn host and post record to this directory of course i dont want to post manually so i worte a script to do that and this is the core thing to do

removes characters from cursor to the end of line

add a backup (or any other) suffix to a file
Very helpful when you've got complex filenames and needs to change just some small parts of it. Renaming a file called "i-made-a-small-typo-right-here" to "i-made-a-big-typo-right-here": $ mv -vi i-made-a-{small,big}-typo-right-here You could also copy multiple files, edit, remove, process, etc.

List folders containing only PNGs

ls -qaltr # list directory in chronological order, most recent files at end of list
I find it very handy to be able to quickly see the most recently modified/created files in a directory. Note that the "q" option will reveal any files with non-printable characters in their filename.

Shell function to exit script with error in exit status and print optional message to stderr
USAGE: die ERRNUM [MESSAGE]

Combining text files into one file

Set name of windows in tmux/byobu to hostnames of servers you're connected to
*I run this with byobu as as a custom status bar entry that runs every 10 seconds by putting it in a script here: $ .byobu/bin/10_update_windows There's no output to stdout, so nothing is displayed on the status bar. *Presumes that #{pane_title} is set to the hostname or prompt containing the host name. In my case, it's in this format: $ $USER@$HOSTNAME:$PWD The sed commands may need to be modified if your pane_title is different. *If you want to strip out a common part of a hostname, add the following before '| uniq' $ -e 's/[COMMON PART]//' I use that to strip out the domain of the servers I connect to, leaving the subdomain.
