Re: [Ilugc] shell script - changing directory
Hi, I was writing a few lines of script to change the *pwd* of my BASH to my *project workspace* whenever i call it (because its a long path) #!/bin/bash DIRECTORY=/home/varrun/Desktop/TODO/Final_yr_project if [ -d $DIRECTORY ]; then echo exists cd $DIRECTORY else echo project directory either wrong or doesnt exist fi When i run it, the directory of my terminal does *not* change i guess because a child process cannot pass arguments to a parent process. Is there any other way i can do this? Well, I think it should not change the directory of the calling terminal, but within the script the directory will change. Try echoing $PWD after the cd command.

2009/12/29 Shakthi Kannan shakthim...@gmail.com Try: $ source your-script.sh Yes, that works, but thats as bad as typing a cd command everytime. I want to run a short command like pc (for project change :) ) by copying it to /sbin 2009/12/29 Abishek Goda goda.abis...@gmail.com Well, I think it should not change the directory of the calling terminal, but within the script the directory will change.

It always helps to know what you are trying to accomplish. Anyways, you could export the PC command in your ~/.bashrc: export PC='cd /path/to/project/directory' Source your ~/.bashrc once: $ source ~/.bashrc and then use: $ $PC SK -- Shakthi Kannan http://www.shakthimaan.com ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc

Re: [Ilugc] shell script - changing directory
export PC='cd /path/to/project/directory' Source your ~/.bashrc once: $ source ~/.bashrc and then use: $ $PC this should work. however there is a better option than exporting command line as a environment variable = specify an alias in bashrc http://linux.about.com/library/glossary/bldef_alias.htm http://www.linux.org/lessons/beginner/l6/lesson6a.html Varrun, this is exactly what you should be doing. There is no need to write a bash script to alias a command. thanks gourav ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc

2009/12/29 Shakthi Kannan shakthim...@gmail.com Everytime? These are new requirements :) You had only asked as to how to cd to a directory from a script. Sorry about that. export PC='cd /path/to/project/directory' Yeah, that works. Thanks. 2009/12/29 Bharathi Subramanian sbhara...@midascomm.com Instead of script, try to use alias command. alias pc='cd /home/varrun/Desktop/todo/project' Yea, that works but only for the current shell. Adding it to the bashrc file should work universally though as Gourav pointed out. 2009/12/30 Raja Subramanian rajasuper...@gmail.com Please read up on Linux Filesystem Hierarchy Standard to learn the directory layout and consider putting your scripts in /usr/local/bin/.
