Clearly depends on your distro: [martijn(a)cow ~]$ which rename /usr/bin/rename [martijn(a)cow ~]$ file $(which rename) /usr/bin/rename: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.18, stripped [martijn(a)cow ~]$ M4

Look at perlfunc. Yes, it is: % file /usr/bin/rename /usr/bin/rename: symbolic link to `/etc/alternatives/rename' % file /etc/alternatives/rename /etc/alternatives/rename: symbolic link to `/usr/bin/prename' % file /usr/bin/prename /usr/bin/prename: a /usr/bin/perl -w script text executable So it is a script on Debian systems (as RedGrittyBrick wrote) and it is part of the "perl" package: % dpkg -S /usr/bin/prename perl: /usr/bin/prename Also as RedGrittyBrick wrote, it isn't part of the perl distribution, but was added by Debian. I don't know why, but from the changelog I can guess that perl 5.005 included rename as an example script, which was included in the perl package, later replaced by an updated script, and the updated is still provided by the perl package even though the example script has been removed from the perl distribution. hp

I can't find it on my elderly Linux server either (find / -name rename). It has perl 5.8.0 from a RedHat RPM package. Maybe rename was removed from perl's examples sometime after perl 5.005? > > Hope this helps, Not as much as I initially thought it would, but thanks. -- RGB

Unfortunately, there is nothing specific to learn in this example. Just the luck of "being at the precise spot at the precise time" (like some kinds of photography! Well, in photography, some people repeat such luck again and again...) >> K:\get-perl\perl>ls perl5.005_03/eg >> ADB client findtar myrup rmfrom sysvipc van >> README down g nih scan travesty who >> cgi dus muck relink server unuc wrapsuid >> changes findcp muck.man rename shmkill uudecode > Maybe rename was removed from perl's examples sometime after perl 5.005? Definitely. This is the latest version on my disk which still has it. Hope this helps, Ilya |
