Shell Programming and Scripting

I have crated a file xx wth env redirected into it 5 times n couldnot proceed further

n next we have to create a script that takes 1 argument being a file, in this instance we use the newly created file above xx(xx file contains the env redirected into it 5 times) read the inputted file, in this case xx and look for occurrences of the current user who is executing the script. On finding an occurrence of the username take that line and append it to a file and display a line number and a bracket against the saved line.

using bash shell

Could you please post type the complete word ' and ' instead of ' n '

So you have env redirected to some file ' xx '.
If looking for occurrences and to print the line number, could use something like this

Code:

awk '/pattern/ {print NR}' inputfile
