Top Forums Shell Programming and Scripting Issues in reading file using 'awk' Post 302781415 by Don Cragun on Saturday 16th of March 2013 01:08:37 PM

What shell are you using where:
Code:
GREP="qcd30"
GREP=""QCD50"
for file in "${GREP[@]}"

creates an array rather than setting grep to the value:
Code:
QCD50
for file in

Even if you get rid of the double double-quote at the start of the second assignment to GREP, GREP still would not be an array.
Have you considered using:
Code:
find top_directory -type d

to generate your list of directories?

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. SEE ALSO
cgrep(1), fgrep(1), sed(1), awk(9). GREP(1)
