How to grep for a string on a FILENAME?

Shell Programming and Scripting
1

I call my bash shell script "test.sh" and pass "admin_usr.txt" as an argument like below.

./test.sh admin_usr.txt

Inside the "test.sh" i wish to check if the filename passed "admin_usr.txt" i.e "$1" contains the string "admin" or not ... which in this case it does.

Note: I do not wish to search contents of the file but only the filename which is being passed as argument.-.

Can you please help me with the if statement ?

if [ `echo $1 | grep -c "admin" ` -gt 0 ]

But i was looking for something simpler.

Still simpler? Not too many options... try

[ $1 = ${1/admin} ]

What i don't understand: if the filename has to contain "admin" and everything else is wrong, why don't you simply add this obligatory string to the parameter passed instead of checking if it is there?

like this:

filename="admin.${1}"

So if you call the script with

yourscript.sh foo

The filename would be "admin.foo", etc.

I hope this helps.
