hex

See the current Perl documentation for hex.

Here is our local, out-dated (pre-5.6) version:


hex - convert a string to a hexadecimal number



hex EXPR

hex



Interprets EXPR as a hex string and returns the corresponding value. (To convert strings that might start with either 0 or 0x see oct.) If EXPR is omitted, uses $_.

    print hex '0xAf'; # prints '175'
    print hex 'aF';   # same

Discipulus uh the link was for cmd.exe the bash one
[marioroy]: If yes, for redirection to work, one might do the following
[marioroy]: `bash -c "clang --version 2>/dev/null"`
[choroba]: Sane people don't use csh
[marioroy]: the 1>&2 will work, not shown
[marioroy]: sorry, did not know which if cmd.exe or unix (bash)
