=>The manual of "grep" command on Red Hat states that:
=>
=>-R, -r, --recursive
=> read all files in each directory, recursively, this is
=>equivalent to -d recurse option
=>
=> --*include*=PATTERN recurse in directories only searching file
=>matching PATTERN
=> --exclude=PATTERN recurse in directories skip file matching
=>PATTERN
=>
=>For the --include or --exclude option, what is "file matching PATTERN"
=>supposed to mean? I supposed it means "file name" match PATTERN, not "file
=>content" match patten, am I right?
=>
=>I'm asking this question, because I'm trying to do the following thing:
=>
=>Find out all plain text files whose file names contain "out" and whose
=>contents containing "zip" (in the form of whole word), and then output
=>these files names to a file called zip.txt. (These plain text files are
=>located in the sub-directories at different levels)
=>
=>I tried the following 2 lines of commands to try to achieve the goal above,
=>but neither worked. Anyone cares to spot the error? I suspect most likely
=>it's because my usage/understanding of --include option is wrong.
=>
=>grep -Hwli -r --include=out "zip" * > zip.txt
=>
=>grep -Hwli --include=out "zip" * > zip.txt
=>
=>Sorry if this question sounds stupid.
That's the dumbest question I ever heard! (just kidding)
It seems to me that you need grep find awk xargs etc...
Tell me if this helps:
find . -type f -name \*out\* | \
xargs file | \
awk '/ASCII/ { sub(/:/, ""); print $1}' | \
xargs grep -l zip > zip.txt
Line 1 gets the list of files whose name contains the word "out".
Line 2 takes that list and runs the file command
Line 3 takes the output of file and prints out column 1 (without the colon
at the end) if the word ASCII is found
Line 4 takes the previous output and searches those files for the word zip
and the output then goes into zip.txt
