Like most developers, I'm always looking for ways to increase my efficiency. One way I like to do this is through Bash functions.
Just like other programming languages, Bash functions allow you to combine Bash commands or manipulate user input to output a desired effect. While I have a good number of Bash functions, today we're going to focus on a simple one: how to copy your present working directory to your clipboard.
While in your terminal, the present working directory (or pwd) is the directory you are currently in. Using the command
pwd will supply you with an output of your current directory.
The other Bash command we're going to use is the
pbcopy command. This command is short for "pasteboard copy" and will take the standard input and paste it on the clipboard. A nice feature of the
pbcopy command is the ability to "pipe" (|) the standard output of one command into the
pbcopy command. We're going to use that to make our Bash function. Put this in your
# Copy the PWD to the Clipboard alias cpwd="pwd | tr -d '\n' | pbcopy && echo 'pwd copied to clipboard'"
Now we can use the command
cpwd to copy our present working directory to the clipboard. I use this frequently for getting the right file paths for symlinks, but there are other uses as well.
Hope this helps!
