Hi,
How are you?
I want to know how to change default directory by shell program
as following:
-----Sample shell---------
#!/bin/csh
cd /usr
ls
----------------------------
After I execute above shell at /, the directory also is / .
so how can I change directory from / to /usr after running shell
program?
Best Regards,
Jun-Mok song

When you execute a shell script, a new shell is spawned to do it. When
it exits, you're back in your original environment, which includes the
original directory. Now if you were to 'source' the script instead of
running it, then the changes will be permanent. If its something you
need all the time, then make an alias. So the script could be called
foo:
----
#!/bin/csh
cd /usr ; ls
---
Then in your .cshrc file, make an alias:
alias lsusr 'source ~/bin/foo'
Then at your command prompt you can just type 'lsusr' to automatically
go to /usr and do a listing (and remain at /usr after the listing).
Or more simply, you could just have the alias be:
alias lsusr 'cd /usr ; ls'
..but that assumes your script is really that simple. The more
complicated your script, the more you'll actually want it to be a
standalone script.

...then start one up in the script. #!/bin/csh cd / csh This is a quick and dirty kludge, since it gives you a couple of extra shell processes. | |||||
