Nl (Unix)

From Free net encyclopedia

nl is a Unix utility for numbering lines, either from a file or from standard input, reproducing output on standard output.

It has a number of switches:

  • a - number all lines
  • t - number lines with printable text only
  • n - no line numbering
  • string - number only those lines containing the regular expression defined in the string supplied.

The default applied switch is t.

nl also supports a number of command line options.
