Linux command-line: Using the 'seq' command to implement 'for' loops in rudimentary shells

When writing shell scripts for Linux/UNIX environments, portability might become an important criterion. If the shell is very rudimentary (like dash, nash, and ash shells), we might need to depend on external commands for most of the shell's shortcomings.

This video will teach you how to use the 'seq' command as an alternative approach to implementing a counting for-loop.
