I'm aware that the correct form for the above is ls -1 /usr/share/man/man1/??.1* | sed -e 's/.*\///' -e 's/\.1.*//'` but the 1.1.5.1 system i've tested this on didn't grok this. So i've used the [/] hackaround that has been working there. According to Posix 1003.2, the latter is the correct form. People who don't like this RE slashomania can also use ls -1 /usr/share/man/man1/??.1* | sed -e 's|.*/||' -e 's/\.1.*//'` instead. Anyway, it's my opinion that several older sed's didn't like anything else than a slash as RE delimiter. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ Never trust an operating system you don't have sources for. ;-)
