In the bash when the user inputs an id to search for the bash currently closes, and if a match is found outputs a new file (match.txt). Is it possible to have not close the bash but rather, on the screen "searching for match" and if a match is found "match found in line.." is displayed and written to match.txt else "no match found" is displayed on the screen and no file is written. Thank you .
The code below downloads a getCSV file then the user enters an id and that input is used to search the getCSV file. Currently, the last part is not working. I have added a loop and modified so other parts of the code with no luck.

grep
GREP(1) General Commands Manual GREP(1)NAME
grep - search a file for lines containing a given pattern
SYNOPSIS
grep [-elnsv] pattern [file] ...
OPTIONS -e-e pattern is the same as pattern
-c Print a count of lines matched
-i Ignore case
-l Print file names, no lines
-n Print line numbers
-s Status only, no printed output
-v Select lines that do not match
EXAMPLES
grep mouse file # Find lines in file containing mouse
grep [0-9] file # Print lines containing a digit
DESCRIPTION
Grep searches one or more files (by default, stdin) and selects out all the lines that match the pattern. All the regular expressions
accepted by ed and mined are allowed. In addition, + can be used instead of * to mean 1 or more occurrences, ? can be used to mean 0 or 1
occurrences, and | can be used between two regular expressions to mean either one of them. Parentheses can be used for grouping. If a
match is found, exit status 0 is returned. If no match is found, exit status 1 is returned. If an error is detected, exit status 2 is
returned.
