BASH Daily — Just An Alternative To Listing Files In A Directory

There are many ways to do the same things in BASH. For example, there is an alternative to `ls` (https://linux.die.net/man/1/ls):

for file in *; do echo ${file}; done

This is practical if your system runs out of memory (e.g.: insufficient memory error).

It can also be useful if you want to do something with each file in a directory.

Here is an example:

for file in * ; \
do cp ${file} ${file.bak}; \
done

This an example where you are creating a copy of each file in a directory.
