Need for work, only a noob. need to search many files for a string "USER HELP", then drop down 1 line and search only next line..
Hi, I'm new to Linux and starting to learn it at work. I need to search many files for a string "USER HELP" if that exists, i need to check the next line down to see if it has "USERHELP=1" under neith it then if it does, pip to a file, have tried and am lost now..
all I have got to is: find . -name "*4gl" | xargs grep "USER HELP" > results
but i think i need a loop..

Have you tried that command without using xargs? As in 'find . -name "*4gl" | grep "USER HELP" > results. What is the exact problem that you are having? Are you not getting output into the file? Are you not getting the correct output?

Ive got this so far:
find /home/malcolm/ -name "*4gl" | xargs grep -n -i --after-context=2 "USER HELP" > /home/malcolm/workdir/aa
but I now need to check to see if 1 line under is not "USERHELP=1" then pip that line number and file to a file.. :)
find /home/malcolm/ -name "*4gl" | xargs grep -n -i --after-context=2 "USER HELP" > /home/malcolm/workdir/aa
but I now need to check to see if 1 line under is not "USERHELP=1" then pip that line number and file to a file.. :)
If a file contains the first line, can you assume it also contains the second line too ?
I mean, if a file contains "USER HELP" can you assume that if the file contains the line "USERHELP" it will be
the following line ?
if yes, then use:
find . -name "*.4gl" -exec grep -e "USER HELP" -e "USERHELP=1" \; -print
Of course you will have to redirect some output to /dev/null if you just want filenames.

Oh, and by the way, the \ at the end of the first line of the command just signifies that the command continues on the next line, you can ignore it and just keep typing.
