Dont give extra spaces before and after = .. So your alias code should be alias run='sh testfile'

And if you need to put that alias in a file and run, then try with ksh shell ..

$ cat file_to_run
alias run='sh testfile'
run
$ ksh file_to_run
/present/home/path
$

# testfile2.sh
alias run='ls -l'

when i run this one also alias name not working for me.

You have to execute the assigned alias within the script itself.

Once you come out of the script, kernel will defaultly unaliases it ..

Incase, if you need to retain the alias value outside the script also .. then try the below ..

$ cat file_to_run
alias run='sh testfile'
$
$ chmod 755 file_to_run
$
$ . ./file_to_run
$
$ run
/present/home/path
$
$

while iam executing . ./file_to_run
it shows /usr/bin/ . permissiondenied.

if i need to retain the alias value outside the script any other possible solutions are there...??

If you retain aliases permanently, then put an entry in corresponding profile files (based on shell) ..

Execute the script as:

. ./scriptname

That is dot-space-dot-slash-scriptname.
The alias will then be retained in the current environment.
