Chained Pipelines
The redirection and piping tokens can be chained together to create complex commands. For example:
ls | grep '\.sh' | sort > shlistlists the contents of the current directory, where this output is filtered to only contain lines which contain .sh, sort this resultant output lexicographically, and place the final output in shlist. This type of construction is used very commonly in shell scripts and batch files.

Famous quotes containing the word chained:
“With a tongue like a razor he will kiss,
the mother, the child,
and we three will color the stars black
in memory of his mother
who kept him chained to the food tree
or turned him on and off like a water faucet....”
—Anne Sexton (1928–1974)
