How to find text files not containing text on Linux?
How do I find files not containing some text on Linux? Basically I'm looking for the invers开发者_Python百科e of the following
find . -print | xargs grep -iL "somestring"
The command you quote, ironically enough does exactly what you describe. Test it!
echo "hello" > a
echo "bye" > b
grep -iL BYE a b
Says a only.
I think you may be confusing -L and -l
find . -print | xargs grep -iL "somestring"
is the inverse of
find . -print | xargs grep -il "somestring"
By the way, consider
find . -print0 | xargs -0 grep -iL "somestring"
Or even
grep -IRiL "somestring" .
You can do it with grep alone (without find).
grep -riL "somestring" .
This is the explanation of the parameters used on grep
-L, --files-without-match
each file processed.
-R, -r, --recursive
Recursively search subdirectories listed.
-i, --ignore-case
Perform case insensitive matching.
If you use l
lowercase you will get the opposite (files with matches)
-l, --files-with-matches
Only the names of files containing selected lines are written
Find the markdown file through find and grep to find the mismatch
$ find. -name '* .md' -print0 | xargs -0 grep -iL "title"
Directly use grep's -L
to search for files that only contain markdown files and no titles
$ grep -iL "title" -r ./* --include '* .md'
If you use "find" the script do "grep" also in folder:
[root@vps test]# find | xargs grep -Li 1234
grep: .: Is a directory
.
./test.txt
./test2.txt
[root@vps test]#
Use the "grep" directly:
# grep -Li 1234 /root/test/*
/root/test/test2.txt
/root/test/test.txt
[root@vps test]#
or specify in "find" the options "-type f"...even if you use the find you will put more time (first the list of files and then make the grep).
