  • attempts to delete all local branches. git will fail on any branches not fully merged into local master, so don't worry about losing work. git will return the names of any successfully deleted branches. Find those in the output with grep, then push null repositories to the corresponding names to your target remote. assumes: - your local and remote branches are identically named, and there's nothing extra in the remote branch that you still want - EDIT: you want to keep your local master branch

    git branch | cut -c3- | grep -v "^master$" | while read line; do git branch -d $line; done | grep 'Deleted branch' | awk '{print $3;}' | while read line; do git push <target_remote> :$line; done

  • extracts path to each md5 checksum file, then, for each path, cd to it, check the md5sum, then cd - to toggle back to the starting directory. greps at the end to remove cd chattering on about the current directory.

    for i in $(find . -name *md5checksum_file* | sed 's/\(\.\/.*\)md5checksum_file.txt/\1/'); do cd "$i"; md5sum -c "md5checksum_file.txt"; cd -; done | tee ~/checksum_results.txt | grep -v "<current directory>"

Show URL/text in clipboard as QR code
Copy a URL (or Thai text, or whatever) and hit the keyboard shortcut for this fu to display it as a QR code. It's an "air gapped" way to send stuff to your phone [unlike google chart API etc.] as long as you watch out for cameras ;). dependencies [sudo apt-get install]: qrencode xclip xloadimage

Search recursively to find a word or phrase in certain file types, such as C code
I have a bash alias for this command line and find it useful for searching C code for error messages. The -H tells grep to print the filename. you can omit the -i to match the case exactly or keep the -i for case-insensitive matching. This find command find all .c and .h files
