Then again, you’ll be able to compress the recordsdata into teams of five, leading to 20 compressed recordsdata in general, and so forth.

#!/bin/bash

# Set the listing trail to the folder containing the recordsdata to be compressed
DIR_PATH="/trail/to/folder"

# Set the title prefix of the output archive recordsdata
ARCHIVE_PREFIX="archive"

# Set the utmost collection of recordsdata in step with batch
MAX_FILES=20

# Trade listing to the required trail
cd "$DIR_PATH"

# Get a listing of all recordsdata within the listing
recordsdata=( * )

# Calculate the collection of batches of recordsdata
num_batches=$(( (${#recordsdata[@]} + $MAX_FILES - 1) / $MAX_FILES ))

# Loop via every batch of recordsdata
for (( i=0; i<$num_batches; i++ )); do
    # Set the start and end indices of the batch
    start=$(( $i * $MAX_FILES ))
    end=$(( ($i + 1) * $MAX_FILES - 1 ))
    
    # Check if the end index exceeds the number of files
    if (( $end >= ${#recordsdata[@]} )); then
        finish=$(( ${#recordsdata[@]} - 1 ))
    fi
    
    # Create a compressed archive document for the batch of recordsdata

    tar -cvzf "$archive_name" "${recordsdata[@]:$get started:$MAX_FILES}"
executed

Obtain this bash script document.

What This Script Does

The above script is a bash script that compresses more than one recordsdata into batch archives.

It first units the trail to the folder (DIR_PATH="/trail/to/folder") containing the recordsdata to be compressed, the title prefix of the output archive recordsdata (ARCHIVE_PREFIX="archive"), and the utmost collection of recordsdata in step with batch (MAX_FILES=20).

It then adjustments the present listing to the required trail and will get a listing of all recordsdata in that listing. The script then calculates the collection of batches of recordsdata and loops via every batch.

For every batch, it units the beginning and finish indices of the batch, assessments if the tip index exceeds the collection of recordsdata, after which creates a compressed archive document for the batch of recordsdata the usage of the ‘tar’ command.

The ensuing compressed archives are named the usage of the prefix specified and numbered sequentially.

Use the Script

Step 1.

To batch zip recordsdata to your Mac, first create a brand new folder and position all of the recordsdata you wish to have to compress within that folder.

For instance, you might want to create a folder known as ‘zipme’ to your Desktop and position all of the related recordsdata within that folder. After you have executed this, you’ll be able to to find the trail to the folder via navigating to it in Finder after which right-clicking and settling on ‘Get Information‘.

Then again, you’ll be able to use the pwd command in Terminal to show the present listing after which append the folder title to the tip of the trail. And in our case, trail to zipme/ is: /Customers/hongkiat/Desktop/zipme, so we will be able to do the next:

edit:

DIR_PATH="/trail/to/folder"

to turning into:

DIR_PATH="/Customers/hongkiat/Desktop/zipme"

 

Step 2.

Reproduction and paste the code above into a brand new document to your Mac the usage of a textual content editor like TextEdit or Atom. Save the document with a .sh extension (e.g. batch_zip.sh) and make it executable via working the next command in Terminal:

chmod +x /trail/to/batch_zip.sh

Step 3.

Then, to run the script, open Terminal and navigate to the listing the place the script is stored. Kind the next command and press Input:

./batch_zip.sh

Observe: If working ./batch_zip.sh doesn’t paintings, check out the usage of sudo ./batch_zip.sh as a substitute. Take into account that “sudo” calls for authorization via getting into the password for the present Mac username.

As soon as finished, all of the recordsdata within the specified folder will probably be compressed into batches of as much as 20 recordsdata every, and an archive document will probably be created for every batch with the required prefix and an incremental quantity.
