     The empty regular expression `//' repeats the last regular

`/REGEXP/'
     This will select any line which matches the regular expression
     REGEXP.  If REGEXP itself includes any `/' characters, each must
     be escaped by a backslash (`\').

     The empty regular expression `//' repeats the last regular
     expression match (the same holds if the empty regular expression is
     passed to the `s' command).  Note that modifiers to regular
     expressions are evaluated when the regular expression is compiled,
     thus it is invalid to specify them together with the empty regular
     expression.

BEGIN{p=0} 是多余的。c 行不打印

1. awk 'p;/c/{p=1}'
