Ήμουν σε ένα σύστημα που δεν είχε αυτό το hack, and reminded me how useful it is. So I thought I would share it with others.
Some of you may know about pushd and popd commands. The pushd is like the cd, but it watches and remembers where you were. You can then display as many levels as you want. It's like a cd but it keeps a history not only for the last time you used it.
The large problem my thing with pushd and popd is that in order for popd to work, i have to remember to do pushd first.
But, like most, from beforechoice, I issue commands in the terminal using the cd command. Until I realize that popd could be useful.
Now the hack.
Just pass him below code in ~/.bashrc:
[pastacode manual=”function%20cd%0D%0A%7B%0D%0A%20%20%20%20if%20%5B%20%24%23%20-eq%200%20%5D%3B%20then%0D%0A%20%20%20%20%20%20%20%20pushd%20~%20%3E%20%2Fdev%2Fnull%0D%0A%20%20%20%20elif%20%5B%20%22%20%241%22%20%3D%20%22%20-%22%20%5D%3B%20then%0D%0A%20%20%20%20%20%20%20%20pushd%20%22%24OLDPWD%22%20%3E%20%2Fdev%2Fnull%0D%0A%20%20%20%20else%0D%0A%20%20%20%20%20%20%20%20pushd%20%22%24%40%22%20%3E%20%2Fdev%2Fnull%0D%0A%20%20%20%20fi%0D%0A%7D” provider=”manual” lang=”php”/]
Και ξεκινήστε ένα νέο shell. Από εκείνο το σημείο και μετά, το cd θα τρέχει το pushd και το popd θα είναι πάντα διαθέσιμο όταν το χρειάζεστε.
Do you have a tip or a trick you want to share? If so, write a comment and we will give it as a post for everyone.
