I have a shell script variable as follows

a='\bin\tem\abc\xyz.sh'

I must remove the xyz.sh from the path and need to store it in a another variable called b. That is b must contain '\bin\tem\abc\'.

You can use Parameter Expansion:

b="${a%\\*}\\"

This removes the trailing \ and everything after it before appending with \.
