There is a directory containing several files and i want to grep for files containing a string "str1" say. for this, the following cmd works perfectly fine :
grep "str1" -r * Now, i want to grep for files which contain two strings say str1 and str2. can anyone please let me know how to do that.
grep "str1" -r -l * Will print just the list of file names of the files with matches so
grep str2 `grep "str1" -r -l *` Should do the job by supplying that lists as the file names input to grep.
Thanks to this answer for the refresher on how to do it.
The following should work for you:
find . -type f -exec sh -c "grep -q str1 {} && grep -q str2 {} && echo {}" \; This would return all files in the current directory (and subdirectories) that contain both str1 and str2.
Another approach is to join the sorted result of two calls to "grep -l"
join <(grep -l "str1" * | sort) <(grep -l "str2" * | sort) 
grep "str1" -r * | grep "str2" this will solve your problem... you could have googled yourself ;)
"str12" and "str2" as the input for the second grep will be the matching lines from the first.
