I need to find all image files from directory (gif, png, jpg, jpeg).
find /path/to/ -name "*.jpg" > log
How to modify this string to find not only .jpg files?

12Does not work for me on mac, but works with the -E (extended) option (maybe the pipe is an extended feature?): find -E /path/to -iregex ".*\.(jpg|gif|png|jpeg)" > log– lingCommented Oct 21, 2015 at 7:38
find /path/to/ \( -iname '*.gif' -o -iname '*.jpg' \) -print0
will work. There might be a more elegant way.

1@Gerald: It's likely you need to group your OR expression in escaped parentheses:
find /path/to/ \( -iname '*.gif' -o -iname '*.jpg' \) -exec ls -l {} \;otherwise the exec only applies to the last part (-iname '*.jpg'in this case). Commented Nov 8, 2018 at 21:50 -
1That's an important remark.
find /path/to/ -iname '*.gif' -o -iname '*.jpg' -print0will only print the jpg files! You need brackets here:find /path/to/ \( -iname '*.gif' -o -iname '*.jpg' \) -print0Commented Feb 11, 2020 at 16:35
find -E /path/to -regex ".*\.(jpg|gif|png|jpeg)" > log
The -E saves you from having to escape the parens and pipes in your regex.

1Hmmm the
-Eoption tellsfindto use "extended regular expressions". Several other tools have a similar option, but I'm not sure this option is available on all UNIX distributions.– tboyce12Commented Aug 18, 2014 at 23:12 -

5@tboyce12 Working on ubuntu, I can specify the -regextype to simplify the regex expression:
find . -regextype posix-extended -regex ".*\.(jpg|gif|png|jpeg)". Commented Oct 23, 2015 at 17:37 -
1@cjm Maybe
find -E /path/to -iregex ".*\.(jpg|gif|png|jpeg)" > log. Using the-iregexflag tellsfindto match case insensitively.– tboyce12Commented Jan 10, 2017 at 23:58
find /path/to/ -type f -print0 | xargs -0 file | grep -i image
This uses the file command to try to recognize the type of file, regardless of filename (or extension).
If /path/to or a filename contains the string image, then the above may return bogus hits. In that case, I'd suggest
cd /path/to
find . -type f -print0 | xargs -0 file --mime-type | grep -i image/

Sorry, had an errant click there and I apparently can't undo the downvote... :( Commented Apr 23, 2016 at 15:56
find /path -type f \( -iname "*.jpg" -o -name "*.jpeg" -o -iname "*gif" \)

2Could you explain why you added the (escaped) parentheses around the name/iname parameters?– user793458Commented Apr 12, 2017 at 14:16

Any reason for the inconsistency?
-iname *.jpg,-o -name *.jpeg,-o -iname *gifall have a slightly different format. Commented Apr 26, 2018 at 6:15 -
if you could at least explain differencies with other answers. Commented May 1, 2019 at 21:50

-o- logical OR. Not an inconsistency, just joins together the-inameclauses.-iname "*gif"would match a filename endingfoogif, whereas-iname "*.gif"would not. Commented Jul 25, 2022 at 17:57
On Mac OS use
find -E packages -regex ".*\.(jpg|gif|png|jpeg)"
In supplement to @Dennis Williamson 's response above, if you want the same regex to be case-insensitive to the file extensions, use -iregex :
find /path/to -iregex ".*\.\(jpg\|gif\|png\|jpeg\)" > log
find -regex ".*\.\(jpg\|gif\|png\|jpeg\)"
Adding -regextype posix-extended option only worked in my case:
sudo find . -regextype posix-extended -regex ".*\.(css|js|jpg|jpeg|png|ico|ttf|woff|svg)" -exec chmod 0640 {} \;
in case files have no extension we can look for file mime type
find . -type f -exec file -i {} + | awk -F': +' '{ if ($2 ~ /audio|video|matroska|mpeg/) print $1 }'
where (audio|video|matroska|mpeg) are mime types regex
&if you want to delete them:
find . -type f -exec file -i {} + | awk -F': +' '{ if ($2 ~ /audio|video|matroska|mpeg/) print $1 }' | while read f ; do
rm "$f"
done
or delete everything else but those extensions:
find . -type f -exec file -i {} + | awk -F': +' '{ if ($2 !~ /audio|video|matroska|mpeg/) print $1 }' | while read f ; do
rm "$f"
done
notice the !~ instead of ~
