grep did not match any "UNF\1122" in the ps output because none of the ps output contained "UNF\1122".
I am not sure what \1122 is supposed to be, but it's some unicode character you may not have noticed because it's probably unprintable in your terminal.
Make sure that it's not actually in your user name:
#!/usr/bin/bash

then
echo "Not valid arguments entered. Just username should be entered."
else
USER_NAME=$1
FILE_NAME=$USER_NAME.info
UNN=STUDIN\\\\$1
echo $UNN
last STUDIN\\\\$1
last UNN
If I type `last STUDIN\\eip060` it works but if I try to expand it with variable it is... (5 Replies)

I want to join two files , with file 1 col 3 and file 2 col 1 as key.
The join command is erratic for some reason. File 2 is a master file having all the names, and file 1 has some values. I want to add the names from fil2 in file 1. If I use the original master file, some output is missing.

grep
GREP(1) General Commands Manual GREP(1)NAME
grep - search a file for a pattern
SYNOPSIS
grep [ option ... ] pattern [ file ... ]
DESCRIPTION
Grep searches the input files (standard input default) for lines (with newlines excluded) that match the pattern, a regular expression as
defined in regexp(6). Normally, each line matching the pattern is `selected', and each selected line is copied to the standard output.
The options are
-c Print only a count of matching lines.
-h Do not print file name tags (headers) with output lines.
-i Ignore alphabetic case distinctions. The implementation folds into lower case all letters in the pattern and input before interpre-
tation. Matched lines are printed in their original form.
-l (ell) Print the names of files with selected lines; don't print the lines.
-L Print the names of files with no selected lines; the converse of -l.
-n Mark each printed line with its line number counted in its file.
-s Produce no output, but return status.
-v Reverse: print lines that do not match the pattern.
Output lines are tagged by file name when there is more than one input file. (To force this tagging, include /dev/null as a file name
argument.)
Care should be taken when using the shell metacharacters $*[^|()= and newline in pattern; it is safest to enclose the entire expression in
single quotes '...'.

Exit status is null if any lines are selected, or non-null when no lines are selected or an error occurs.
