AI Command Line history unix

Since its inception in 1977 awk enjoyed a user base of thousands of people.

Since LLMs can tell us how to use it now, it suddenly became millions.

getting shells in the same path

Command Line linux technology

Often I work with a couple of shells simultaneously in the same directory. One may be the editor with a program in it, and the other one running it.
When I add the following lines to .bashrc

alias sd='pwd > /tmp/ddd'
alias d='cd `cat /tmp/ddd`; pwd'

I just need to type ‘sd’ (for Set Directory) in a shell that is already in the right directory. When I then log in with the other shell a simple ‘d’ gets me where the other shell already is. Extra benefit: When I want to continue where I was last I just type ‘d’ again. Just a little thing. But the world is made out of little things. Lots and lots of them.
