I am currently running the below jpegoptim command via cron to have jpegoptim look for jpg files to compress.
find /home/public_html/public/uploads -name '*.jpg' -type f -print0 | xargs -0 jpegoptim -o -p --size=300k --strip-all
This works, but is there a way to include .jpeg, .JPG, and .JPEG without having to run the same command multiple times? Also, is it okay to run every hour, or would this keep compressing the same files eventually reducing the quality?
You can match all of *.jpg, *.JPG, *.jpeg, *.JPEG by using two case-insensitive name matches.
find /home/public_html/public/uploads \
'(' -iname '*.jpg' -o -iname '*.jpeg' ')' -type f -print0 \
| xargs -0 jpegoptim -o -p --size=300k --strip-all
You can keep a separate timestamp to avoid reprocessing the same files, for example
find /home/public_html/public/uploads \
-newer .STAMP '(' -iname '*.jpg' -o -iname '*.jpeg' ')' -type f -print0 \
| xargs -0 jpegoptim -o -p --size=300k --strip-all
touch .STAMP

I'm using pdftotext and find to find the contents of a PDF file and move it. I can find all of the files, but trying to add the mv command to the end with xargs returns "No such file or directory" for each file.
My code is as follows:
find ./ -name '*.pdf' -exec sh -c 'pdftotext "{}" - | grep -l -Z -i --with-filename --label="{}" --color "Thank you" | xargs -0 -I{} mv {} Found/' \;
Is xargs not getting the correct file path? I'm not sure what is happening.
you can get this, when the names contain spaces. Could you try this.
find ./ -name '*.pdf' -not -path "./Found/*" -exec sh -c 'pdftotext "{}" - | grep -l -Z -i --with-filename --label="{}" --color "Thank you"' \; | xargs -0 -I{} mv {} ./Found/
I need to place a command that will search for all files in the current directory as well as in its sub-directories - ending by ~, and/or all files that start or end by #. The command line will show and erase all files found. Only one command is allowed: no ’;’ or ’&&’ or other shenanigans.
here is my command:
find . -name "#*" -o -name "*#" -o -name "*~" -print -delete
but it erases only the files ending in ~
You forgot to enclose the conditions with parenthesis (). This means that only the last condition will trigger the actions -print and -delete.
The default is and -a, which would not require the parenthesis, that's why most find commands such as find -type f -name "pattern" -print works without parenthesis.
You should try:
find . \( -name "#*" -o -name "*#" -o -name "*~" \) -print -delete
How about -print0 primary in conjunction with xargs -0'' like this .
find . -type f -print0 | xargs -0 rm
za:temp za$ ls
file.txt file.txt~
za:temp za$ find . -name "*~" -print0 | xargs -0 rm
za:temp za$ ls
file.txt
Or with xargs -I {} plus your comand which does the same thing .
# xargs -I {} to capture the value of find
find . -iname *something* | xargs -I {} rm {}
edit : if you can't see the files that start with # using find . then the files have spaces within the name of the file(s) like # file.txt. you will need to find files with spaces with something like find . -name "* *" and then remove the spaces.
I recently found out this solution to less through compressed gz files parellelly based on the cores available.
find . -name "*.gz" | xargs -n 1 -P 3 zgrep -H '{pattern to search}'
P.S. 3 is the number of cores
I was wondering if there was a way to do it for bz2 files as well.
Currently I am using this command:
find -type f -name '*.bz2' -execdir bzgrep "{text to find}" {} /dev/null \;
Change *.gz to *.bz2; change zgrep to bzgrep, and there you are.
For a bit of extra safety around unusual filenames, use -print0 on the find end and -0 on the xargs:
find . -name "*.bz2" -print0 | xargs -0 -n 1 -P 3 bzgrep -H '{pattern to search}'
I currently have this script to compress log files:
find . -name '*.log' -print0 | xargs -0 tar zcf $file
Currently finds and compress all the *.log files. I would like to modify it to include also all the ".txt" files but I don't know how, this should be fairly simple right?
find . -type f \( -name "*.log" -o -name "*.txt" \) -exec tar zcf "$file" {} +
Alternatively:
find . -type f -regex ".*\.\(txt\|log\)$" -exec tar zcf "$file" {} +
No need for xargs if your version of find is POSIX compliant and can have it's -exec command terminated with a + (most can)
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?
find /path/to -regex ".*\.\(jpg\|gif\|png\|jpeg\)" > log
find /path/to/ \( -iname '*.gif' -o -iname '*.jpg' \) -print0
will work. There might be a more elegant way.
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.
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/
find /path -type f \( -iname "*.jpg" -o -name "*.jpeg" -o -iname "*gif" \)
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 ".*\.\(jpg\|gif\|png\|jpeg\)"
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 ~
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 {} \;
