If you work regularly in Linux shells and are navigating through the directories, you may find yourself deep in some directory structure like /home/bla/test/other/and/another/dir and you want to come up to other. The two obvious commands here are /home/bla/test/other/and/another/dir and cd ../../../. Sometimes you might be deeper in the shit and if you are regular into this, you might it annoying some times.
Today I came across a tip while browsing through this Quora Answer, which explains how can we make our life easier in this case.
If you are using Bash, put below code in your .bash_profile file. And then you can use up other directly to come up to other directory in above example.
function up {
cd `expr "$PWD" : "^\(.*$1[^/]*\)"`
}
Since, CSH do not support the functions, I converted it to alias. You can put this in your .cshrc and use it as <span class=“text”>up other</span>
alias up 'cd `expr "$PWD" : "\(.*\!*[^/]*\)"`'
Happy shell scripting.
