To check the file size in a Linux or Unix bash shell script, you can use the du command. The du command is a utility that is used to estimate the space used by a file or directory.
Here's an example of how to use the du command to check the file size in a bash shell script:
size=$(du -b /path/to/file | cut -f1) echo "The size of the file is $size bytes"
This script will print the size of the file in bytes.
You can also use the stat command to check the file size. The stat command is a utility that is used to display information about a file or filesystem.
Here's an example of how to use the stat command to check the file size in a bash shell script:
size=$(stat -c%s /path/to/file) echo "The size of the file is $size bytes"
This script will also print the size of the file in bytes.
