  • 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. Show Sample Output

    mv -vi file{,~}

  • This lengthy cryptic line will print the latest top 10 posts without their summaries. To print also their respective summaries use the following (even bigger) command line: wget -qO - | xmlstarlet sel -T -t -o '<doc>' -n -t -m rss/channel/item -o '<item>' -n -o '<title>' -v title -o '</title>' -n -o '<description>' -v description -o '</description>' -n -o '</item>' -n -t -o '</doc>' | xmlstarlet sel -T -t -m doc/item -v description/code -n -v title -n -n It is recommended to include this line into a shell script to be easily run, as I do myself. You could also use the following URLs to browse the top 3 commands: wget -qO - | xmlstarlet ... .. or all others: wget -qO - | xmlstarlet ... PS: You need to install "xmlstarlet" to run it. It is found in Debian APT repositories (apt-get install xmlstarlet) or under the URL. Show Sample Output

    wget -qO - | xmlstarlet sel -T -t -o '&lt;x&gt;' -n -t -m rss/channel/item -o '&lt;y&gt;' -n -v description -o '&lt;/y&gt;' -n -t -o '&lt;/x&gt;' | xmlstarlet sel -T -t -m x/y -v code -n

  • This command will find the biggest files recursively under a certain directory, no matter if they are too many. If you try the regular commands ("find -type f -exec ls -laSr {} +" or "find -type f -print0 | xargs -0 ls -laSr") the sorting won't be correct because of command line arguments limit. This command won't use command line arguments to sort the files and will display the sorted list correctly. Show Sample Output

    find . -type f -printf '%20s %p\n' | sort -n | cut -b22- | tr '\n' '\000' | xargs -0 ls -laSr

What's this? is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Get gzip compressed web page using wget.
Like the original command, but the -f allows this one to succeed even if the website returns uncompressed data. From gzip(1) on the -f flag: If the input data is not in a format recognized by gzip, and if the --stdout is also given, copy the input data without change to the standard output: let zcat behave as cat.

Create an test virus
Test whether real-time virus detection is working by running this command and checking for in /tmp. Requires real-time scanning to be enabled and active on the /tmp directory. If scanning is active, the file should be quarantined/deleted (depending on your settings) moments after running this command. If not, the (harmless) test file should remain in your /tmp directory.
