awk's sub function needs two or three parameters; you supply but one. awk uses regexes, not (shell) patterns; the latter uses * for a wildcard char, the former [ICODE] . [/ICODE, optionally followed by a repetition char, one of which would be * . But, beware of false matches - e.g. a / would match as well.
I'd propose to consult man awk.
However, try this amended version of your command: ---------- Post updated at 12:38 ---------- Previous update was at 12:33 ----------
or a shortcut version:
---------- Post updated at 12:42 ---------- Previous update was at 12:38 ----------
And , to your boss' wishes: how familiar are you with shell functions and shell parameters? And the case ... esac construct?
Both worked! I decide to opt for the shorter version. I think I tried sub (".*/", at one point, but didn't realize I needed a 2nd or even 3rd item in there for it to work. I was so close!
I can't thank you enough for your help. I've told the boss that you have helped me out too because you deserve the credit for helping a noob out, even if you two have no idea who the other is.
Whenever I finish building this out, I'll post my results. It may end up helping someone in a similar situation in the future!
I am performing a grep command and I need to know how to echo "NONE" or "0" to my file if grep does not find what i am looking for.
echo What i found >> My_File
grep "SOMETHING" >> My_File
I am sure this is easy, I am sort of new at this!

I'm having problems since few days ago, and i'm not able to make it works with a simple awk+grep script (or other way to do this).
For example, i have a input file1.txt:

SYNOPSIS
info [OPTION]... [MENU-ITEM...]
DESCRIPTION
Read documentation in Info format.
OPTIONS --apropos=STRING
look up STRING in all indices of all manuals.
-d, --directory=DIR
add DIR to INFOPATH.
--dribble=FILENAME
remember user keystrokes in FILENAME.
-f, --file=FILENAME
specify Info file to visit.
-h, --help
display this help and exit.
--index-search=STRING
go to node pointed by index entry STRING.
-n, --node=NODENAME
specify nodes in first visited Info file.
-o, --output=FILENAME
output selected nodes to FILENAME.
-R, --raw-escapes

--subnodes

The first non-option argument, if present, is the menu entry to start from; it is searched for in all `dir' files along INFOPATH. If it is
not present, info merges all `dir' files and shows the result. Any remaining arguments are treated as the names of menu items relative to
the initial node visited.
EXAMPLES
info show top-level dir menu
info emacs
start at emacs node from top-level dir
info emacs buffers
start at buffers node within emacs manual
info --show-options emacs
start at node with emacs' command line options
info -f ./foo.info
