  • 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

  • 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.

    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
