  • Determine command type (alias, keyword, function, builtin, or file)

    Prints a string indicating whether a command is an alias, keyword, function, builtin, or file. I have used this in my BASH scripts to allow an external parameter to define which function to run, and ensure that it is a valid function that can indeed be run. Show Sample Output

    type -t $1

  • How to delete all the archive files with extension *.tar.gz and greater than 10MB?

    Please be careful while executing the following command as you don?t want to delete the files by mistake. The best practice is to execute the same command with ls ?l to make sure you know which files will get deleted when you execute the command with rm.


    0
    find / -type f -name *.tar.gz -size +10M -exec ls -l {} \;

  • Adds "-c" canonical option to bash "type" builtin command to follow symbolic links

    The "type" builtin command is handy to find out what executable will be used if you issue a command. But on some distros, particularly when using /etc/alternatives, certain executables get buried under layers and layers of symbolic links and it becomes hard to find which one. If you put the above command in your .bashrc, it adds a "-c" option to the type command that will weed through the symbolic links and prints the actual file that will be executed. Show Sample Output


    0
    type () { if [ "$1" = "-c" ]; then shift; for f in "$@"; do ff=$(builtin type -p "$f"); readlink -f "$ff"; done; else builtin type $typeopts "$@"; fi; }

  • What Type of Computer Do You Have?

    Prints the type of computer you have. I think this should be used more in distros and other applications because it is so easy to get. This can also be asked by tutorials as an easy way to get your base hardware. Some alternatives: sudo dmidecode -s system-product-name and sudo smbios-sys-info-lite | sed -n 's/^Product Name: *\(.*\)/\1/p' Show Sample Output


    -2

recursive search and replace old with new string, inside files
Using -Z with grep and -0 with xargs handles file names with spaces and special characters.

Convert CSV to JSON
Replace 'csv_file.csv' with your filename.

Clear current session history (bash)

Sort all running processes by their memory & CPU usage
you can also pipe it to "tail" command to show 10 most memory using processes.

BourneShell: Go to previous directory
cd - would return to the previous directory of your cd command. NB: previous dir is always stored in $OLDPWD variable.

Copy a file using dd and watch its progress
This is a more accurate way to watch the progress of a dd process. The $DDPID=$! is needed so that you don't get the PID of the sleep. The sleep 1 is needed because in my testing at least, if you run kill -USR1 against dd too quickly, it will kill it off instead of display the status. So you need to wait a second, probably so that it can configure itself to trap the USR1 signal.

clear the X clipboard
Clears your clipboard if xsel is installed on your machine. If your xsel is dumb, you can also use $xsel --clear --clipboard

Convert all Flac in a directory to Mp3 using maximum quality variable bitrate

sync svn working copy and remote repository (auto adding new files)
Lists the local files that are not present in the remote repository (lines beginning with ?) and add them.
