thanx hemo
I wrote in pc program that has file inpun like this:
s /data/source
br /home/baruch
u /user/bin
...
it called cdn with parameter of the first 2 characteres of
the input file, for exmp. cdn br.
the output of that program is "cd /home/baruch".
in unix the cd only efected on the shell scripet and
after exit to the kernel the prmpt didn't switched to the
disaire folder.
who can i do that in unix evairoment.
thanx for advance

S="/data/source"
BR="/home/baruch"
U="/user/bin"
export S BR U
-----
cd $S
cd $BR
cd $U
The 'export' command will export the variables so they can be used after the shell program exits.
I recommend using uppecase monikers, since a lot of nonsense seeming lowercase ones may actually be unix commands and you could get unexpected results.
Is this more of what you are looking for?
Having a shell script physically move you to a new folder and then exit, leaving you in the new directory.. I've not done that other than spawning a new shell in the new directory, when exiting a shell, I am always left in the directory I called the original shell from.
BR="/home/baruch"
U="/user/bin"
export S BR U
-----
cd $S
cd $BR
cd $U

First sorry for my poor english....
I will give u other example.
1. i have a sh scrept like this. (called a).
A="/home/val" ;export A
cd $A
pwd
2. from the my prompt korn shell:
/abic0/prgmrs/baruch> sh -x a
+ A=/home/val
+ export A
+ cd /home/val
+ pwd
/home/val
/abic0/prgmrs/baruch>
3. My target was to be physically after exit scipt a
in the koren shell prompt, in /home/val directory.
4. in pc dos, i have a nice tool like bookmark.
directories i want frequent switch to them.
i have a txt file like above, and a cobol program
called CDN, that can execute pc command from inside,
so when i type CDN m , the dos prompt switched to c:\ms.
Most gegarts to your attention,
Barry

The command /abic0/prgmrs/baruch> sh -x a
forks a child process.
A child process can never modify the parent environment.
The cd $a in the child process, is lost as soon as the child process exits.
If you want to run a script that modifies the parent process, you need to "source" , or "dot" execute the script.
