bash using awk in xargs shell command

Comment

# Basic syntax:
input_command | xargs -I {} sh -c 'awk '\''your_awk_command'\'' {}'
# Where:
#	- the STDOUT of the input_command is piped to xargs
#	- -I {} specifies the pattern that xargs will look for and replace with the
#		information that gets piped to xargs
#	- sh -c '...' is used to run shell commands, in this case, an awk command
#	- '\'' according to the source, this ends the single-quoted literal, then
#		adds a single quote which is interpreted literally due to the preceding
#		backslash, then starts another single-quoted literal
#	Note, using '\'' helps avoid having to escape $s in your awk command

# Example usage:
# Say you want to see the extensions of the files in the current folder.
# You can run an xargs command with awk like this:
find . -maxdepth 1 -type f | xargs -I {} sh -c 'echo {} | awk '\''{split($0, a, "."); print(a[2])}'\'''
# Note, there are better non-xargs non-awk ways of doing this, but this
#	demonstrates the syntax
