xargs – build and execute command lines from standard input
This manual page documents the GNU version of xargs. xargs reads items
from the standard input, delimited by blanks (which can be protected with double or single
quotes or a backslash) or newlines, and executes the command (default is /bin/echo)
one or more times with any initial-arguments followed by items read from standard
input. Blank lines on the standard input are ignored.
Because Unix filenames can contain blanks and newlines, this default behaviour is often
problematic; filenames containing blanks and/or newlines are incorrectly processed by xargs.
In these situations it is better to use the -0 option, which prevents such problems.
When using this option you will need to ensure that the program which produces the input
for xargs also uses a null character as a separator. If that program is GNU find for example,
the -print0 option does this for you.
