If you forever need to zip large numbers of files for your Mac, you’ll have found out the technique to be time-consuming and repetitive. While the Archive Software built into Mac OS can be used to zip files in batches, it could most definitely however be a information process. On the other hand, with fairly little little bit of scripting knowledge, you’ll be capable to automate the process of batch zipping files the use of a Bash script.
In this article, we can data you at some stage in the process of constructing a Bash script that permit you to zip files in batches of any amount you choose, for your Mac. Whether or not or now not you could be operating with plenty or 1000’s of files, this script will mean you can save time and avoid the monotony of zipping files manually. By the use of the end of this tutorial, you’re going to have a fully-functional Bash script that you just’ll be capable to use to batch zip files in any quantity you wish to have, with just a few simple directions.
For example, let’s say you’ll have 100 files in a particular folder. You’ll use this script to compress the files into groups of 10, main to ten compressed files usually. On the other hand, you’ll be capable to compress the files into groups of 5, main to twenty compressed files usually, and so on.
#!/bin/bash
# Set the checklist path to the folder containing the files to be compressed
DIR_PATH="/path/to/folder"
# Set the identify prefix of the output archive files
ARCHIVE_PREFIX="archive"
# Set the maximum number of files consistent with batch
MAX_FILES=20
# Business checklist to the desired path
cd "$DIR_PATH"
# Get an inventory of all files inside the checklist
files=( * )
# Calculate the number of batches of files
num_batches=$(( (${#files[@]} + $MAX_FILES - 1) / $MAX_FILES ))
# Loop by way of each and every batch of files
for (( i=0; i= ${#files[@]} )); then
end=$(( ${#files[@]} - 1 ))
fi
# Create a compressed archive file for the batch of files
archive_name="${ARCHIVE_PREFIX}_${i}.tar.gz"
tar -cvzf "$archive_name" "${files[@]:$get began:$MAX_FILES}"

What This Script Does
The above script is a bash script that compresses a couple of files into batch archives.
It first gadgets the path to the folder (DIR_PATH="/path/to/folder") containing the files to be compressed, the identify prefix of the output archive files (ARCHIVE_PREFIX="archive"), and the maximum number of files consistent with batch (MAX_FILES=20).
It then changes the existing checklist to the desired path and can get an inventory of all files in that checklist. The script then calculates the number of batches of files and loops by way of each and every batch.
For each and every batch, it gadgets the start and end indices of the batch, exams if the end index exceeds the number of files, and then creates a compressed archive file for the batch of files the use of the ‘tar’ command.
The following compressed archives are named the use of the prefix specified and numbered sequentially.
Use the Script
Step 1.
To batch zip files for your Mac, first create a brand spanking new folder and place all the files you need to compress inside of that folder.
For example, you may need to create a folder referred to as ‘zipme’ for your Desktop and place all the similar files inside of that folder. Upon getting achieved this, you’ll be capable to to search out the path to the folder by way of navigating to it in Finder and then right-clicking and selecting ‘Get Knowledge‘.
On the other hand, you’ll be capable to use the pwd command in Terminal to turn the existing checklist and then append the folder identify to the end of the path. And in our case, path to zipme/ is: /Shoppers/hongkiat/Desktop/zipme, so we can do the following:
edit:
DIR_PATH="/path/to/folder"
to becoming:
DIR_PATH="/Shoppers/hongkiat/Desktop/zipme"
Step 2.
Replica and paste the code above into a brand spanking new file for your Mac the use of a text editor like TextEdit or Atom. Save the file with a .sh extension (e.g. batch_zip.sh) and make it executable by way of running the following command in Terminal:
chmod +x /path/to/batch_zip.sh
Step 3.
Then, to run the script, open Terminal and navigate to the checklist where the script is saved. Type the following command and press Enter:
./batch_zip.sh
Follow: If running ./batch_zip.sh doesn’t art work, take a look at the use of sudo ./batch_zip.sh as an alternative. Remember that “sudo” requires authorization by way of entering the password for the existing Mac username.
Once completed, all the files inside the specified folder it is going to be compressed into batches of up to 20 files each and every, and an archive file it is going to be created for each and every batch with the desired prefix and an incremental amount.
