Let’s assume your images are stored in ~/Pictures which is shorthand for /home/USER_ID/Pictures. Place the following commands in your home directory in a script file called CompressImages. Make the file executable using:
chmod a+x ~/CompressImages
Call the script using:
~/CompressImages
Copy the following script into the file ~/CompressImages:
#!/bin/bash
# Where to store Tars? We don't want in Images directory
COMPRESSED_DIR="$HOME/Downloads"
# TARs created with name below + "_999.tar"
TAR_NAME="CompressedImages"
# Directory Images are located in
FILES="$HOME/Pictures/*"
FileCount=50 # Number of files compressed into one Tar
TarCount=0 # Count of Tars created
i=0
for f in $FILES
do
if [[ $(( i % FileCount )) -eq 0 ]] ; then
let TarCount++
TarName="$COMPRESSED_DIR/$TAR_NAME$TarCount.tar"
tar -cvpf "$TarName" "$f" # create .tar & add first file
else
tar -rvpf "$TarName" "$f" # Add to existing tar
fi
let i++
done
After running CompressImages script check the results:
$ ll -h ~/Downloads/*.tar
