Playing with xargs
We use pipes to redirect
stdout (standard output) of a command to
stdin (standard input) of another command. For example:
cat foo.txt | grep "test"
But, some of the commands accept data as command-line arguments rather than a data stream through
stdin (standard input). In that case, we cannot use pipes to supply data through command-line arguments.
We should go for alternate methods.
xargs is a command that is very helpful in handling standard input data to the command-line argument conversions.
xargs can manipulate
stdin and convert to command-line arguments for the specified command. Also
xargs can convert any one line or multiple line text input into other formats, such as multiple lines (specified number of columns) or a ...
