Find & grep

postcd · 11-25-2014, 11:08 AM

i used "grep -f my_phrasses.txt filename" as a part of linux Find command.
But the result is the phrasses not file names/file paths which is what i need..

i need to search millions of files and 20 phrasses in each of the file that match Find parameters...

this is end of my Find command:
-exec grep -f my_phrasses.txt {} \;

any idea how to return file pathes, not phrasses from my_phrasses.txt while maintaining low memory, cpu impact of the command? thx

change to

Code:

-exec grep -qf my_phrasses.txt {} \; -exec echo {} \;

Code:

-exec grep -l -f my_phrasses.txt {} +

This will pass the maximum allowed number of file paths to each grep invocation rather than invoking grep separately for each file. With the "-l" option, grep will print (just) the filename and proceed to the next file immediately when it finds a match, rather than continuing to search the rest of the current file.
