Bash Quick Tip - Subshells
When you’re in a shell, and you want to do 1 or 2 commands in another brand new shell, but don’t feel like opening a new window, try using a subshell.
Here’s an example:
~ jhaddad$ pwd /Users/jhaddad ~ jhaddad$ ( cd /tmp/; touch bacon.txt ) ~ jhaddad$ pwd /Users/jhaddad ~ jhaddad$ ls -lah /tmp/bacon.txt -rw-r--r-- 1 jhaddad wheel 0B Apr 15 13:09 /tmp/bacon.txt
Why I like it: I can very quickly fire off a command that involves changing directories without having to switch back to my pwd.If you found this post helpful, please consider sharing to your network.
