Shell Programming and Scripting

hey why don't u jst post all the lines that u executed along with the o/p u see on ur screen... line by line....
show us what exactly u type and what happens.
if theres' an undefined variable then there may be a spelling mistake in the variable "input" that u used...

correct maybe your input directory is wrong.

One other way that works on my system is

Code:

$ source change.sh
bash: !#/bin/sh: No such file or directory
please enter dir
/home

nua7@XX0703328304 /home
$

I made a script using VI editor called "script", save the file at /home/blah/test


#!/bin/sh

echo "Please enter the dir"
/home/blah

read input
echo $input
/home/blah

cd $input

go back to prompt.
and when i do "PWD" command, i'm still at /home/blah/test

when i run the script using

# . ./script

please enter dir
/home/blah
input: Undefined variable.

#

what do u type in at the read input line?
does the directory exist???
in short:
carry out the following steps:
1. create a directory
$ mkdir varun
2. create a file change.sh and type in the nxt 2 lines
$ vi change.sh
~echo "enter a directory"
~read dir
~cd $dir
~
~
3. save the file and exit.
:wq!
"change.sh" 3L, 48C written
4. Now run this file
$ . change.sh
enter a directory:
varun
varun$

This thread has carried on too far now.
Just follow the steps above.
If it doesn't work then lets assume that u r using a customized version of unix which may have some differences.....
or u might not be disclosing all the relevant info thats needed
