What is basename in bash script?
In Linux, the basename command prints the last element of a file path. This is especially useful in bash scripts where the file name needs to be extracted from a long file line. The “basename” takes a filename and prints the filename’s last portion. It can also delete any following suffix if needed.
What is the opposite of basename?

What is Dirname in bash?
What is a bash dirname command? Dirname is a built-in command on Linux and Unix-like OSes; it is used to identify paths in shell scripts. Simply, dirname will remove the last part of a filename, after the last forward-slash (/), and print the remaining command as the name of the directory where that file is saved.
What is a file’s basename?
A file path is a string containing one or more segments consisting of names separated by directory delimiter characters (slash (/) under UNIX, or backslash (\) under Microsoft Windows).

What is the difference between awk and gawk?
DESCRIPTION Gawk is the GNU Project’s implementation of the AWK programming language. As for speed, using gawk as “plain” awk should make no difference – often, when gawk is installed, awk will just be a symlink to gawk which means they’ll be exactly the same program.
Is awk worth learning?
awk is a powertool language, so you are likely going to find awk being used somewhere if you are an IT professional of any sort. If you can handle the syntax and regular expressions of grep and sed then you should have no problem picking up awk and it is probably worthwhile to.
