-p printf_format |
use this printf format for IP address and hostname, respectively. The
default format is '%.0s%s', which supresses the printing of the IP address
(i.e. "%.0s" specifies printing a string with a maximum width of
zero). To maintain column widths (since both the IP address and hostname
vary in lenght), a format like this may be useful: '%-16.16s %-20s'
(mnemonic: 'p'rintf format) |
-i extension |
edit the files in place (rather than sending to standard output) This
option requires file name(s) argument(s). The extension is added to the
name of the old file to make a backup copy. If you don't wish to make a
backup, use "-I". (mnemonic: edit 'i'n place) |
-I |
like "-i" but no backup is made. (mnemonic: edit 'I'n place,
trusting this script 'I'mplicitly. ;^) |
