Check These Out

Search back through previous commands
Searches backwards through your command-history for the typed text. Repeatedly hitting Ctrl-R will search progressively further. Return invokes the command.

Check whether laptop is running on battery or cable
If you want to do the same in OS X... grep as necessary for information you need....

Give any files that don't already have it group read permission under the current folder (recursive)
Makes any files in the current directory (and any sub-directories) group-readable. Using the "! -perm /g=r" limits the number of files to only those that do not already have this property Using "+" on the end of the -exec body tells find to build the entire command by appending all matching files before execution, so invokes chmod once only, not once per file.

Change a specific value in a path
Awk replaces the value of a specific field while retaining the field separator "/" .

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

Save a file you edited in vim without the needed permissions
Calls sudo tee like all the other lines, but also automatically reloads the file. Optionally you can add command Wq :execute ':W' | :q and command WQ :Wq to make quitting easier

a function to create a box of '=' characters around a given string.
First argument: string to put a box around. Second argument: character to use for box (default is '=') Same as command #4962, cleaned up, shortened, and more efficient. Now a ' * ' can be used as the box character, and the variables get unset so they don't mess with anything else you might have. They marked c++ as a function for this command, but I'm not sure why. Must be a bug.

Look for English words in /dev/urandom
Little faster alternative.

Restart openssh-server on your Synology NAS from commandline.
The correct way to restart openssh-server on your synology nas.

Detect encoding of a text file
This command gives you the charset of a text file, which would be handy if you have no idea of the encoding.
