NAME¶

pfgrep - grep out function definitions from perlfunc

DESCRIPTION¶

This program uses podgrep program to search your configuration's perlfunc for function definitions. It honors a -f flag to format through pod2text and a -p flag to send the output through the pager. (Actually, it just passes these to podgrep.)

EXAMPLES¶

    $ pfcat seek
    (find all seek functions (including sysseek))
    $ pfcat -pf sprintf
    (sprintf function is formated and sent to pager)
    $ pfcat -f '\bint\b'
    /usr/local/devperl/lib/5.00554/pod/perlfunc.pod chunk 506
    int EXPR
    int
    Returns the integer portion of EXPR. If EXPR is omitted, uses
    `$_'. You should not use this for rounding, because it truncates
    towards `0', and because machine representations of floating point
    numbers can sometimes produce counterintuitive results. Usually
    `sprintf()' or `printf()', or the `POSIX::floor' or `POSIX::ceil'
    functions, would serve you better.

You can also run this using alternate perl binaries, like so:

    $ oldperl -S pfcat open
    ....
