Delete file based on file size

Fixit7 · 08-24-2016, 06:54 PM

I am interested in a script that would delete a file based on it's file size.

Ex.

Delete any .sh files that are less than 58 bytes.

This come close, it find files less than 57 bytes.

I need it to find files that are exactly 57 bytes.

sudo find . -name "*.sh" -size -57w

I need it to find files that are exactly 57 bytes.

Code:

find . -name "*.sh" -size -58w -size +56w

Although I think +56c, -58c would be for bytes...? (I show w figuring that you know you want 2-byte words)

See michalek below... I didn't realize that, but is in line with other find options.

-size +xx will find files larger
-size xx will find exact file size
-size -xx will find files smaller

c is for bytes and w for two byte words.

Thanks.

This is my finished script.

#!/bin/bash
# Ubuntu_Mate

# Create script template that includes commented date and time
#
# Saves a lot of typing :-)
# Delete scripts of exactly 57 bytes
# Those files are scripts that contain no bash commands
find . -name "*.sh" -size 57c -delete
# Create a script template that includes a commented date and time
echo '#!/bin/bash' > new.sh
echo "# Ubuntu_Mate" >> new.sh
echo '#' $(date) >> new.sh
# Open geany editor and create new script
geany new.sh
# If no file changes, delete new.sh
find . -name "*.sh" -size 57c -delete
