[SOLVED] Thorough search for a text file with a specific keyword inside

educateme · 10-11-2013, 06:12 AM

I seem to have lost a specific file of mine. I forgot its name and the directory it is in, but I know what is inside. I know that (1) the filename ends in ".txt" and (2) I know a unique keyword that I am sure is inside this text file (say, "mykeyword"). Armed with these two facts, what is the best/fastest linux command that I can use to search my entire disk for this specific file?

Code:

locate -0 '*.txt' | xargs -0 grep mykeyword

Code:

find / -name "*.txt" -exec grep mykeyword {} \;

while slower, doesn't rely on the "locate" database being up-to-date

Thanks for the replies. I was not successful with the locate command. I might have an obsolete database.

Code:

find / -name "*.txt" -exec grep mykeyword {} \;

was semi-successful: it managed to display the line in which "mykeyword" was in the file I was looking for. But unfortunately the filename nor the path to this file was not displayed, just the single line inside the file. So I unfortunately still can't locate the file.

try:

Code:

 grep -H mykeyword

-H tells grep to give the filename

Splendid!

Code:

find / -name "*.txt" -exec grep -H mykeyword {} \;

works. Thanks.
