Can someone please explain why bash sucks? Everyone keep's saying this but I have never heard anyone explain why, other than the GPL issue. I really want to know. (This is not because I'm a bash fan. My personal favorite happens to be zsh.) > I tried replacing /bin/bash with /bin/ksh on a Linux system and it > almost completely broke it.

However, if your intent (and the intent of Chuck Robey in that earlier) post is to imply that it's bad programming practice to write anything than POSIX compatible scripts, then I have to ask again - why? This is kind of a pet peeve of mine, so here goes somewhat of a rant. Please enlighten me as to why I am wrong: I don't understand why everyone insists on POSIX compliance for portability with shell scripting. The POSIX common demoniator seems to suck. Seriously. One keeps seeing things like: if [ x"$var" = x"value" ] When the intent is: if [ "$var" = "value" ] Because there is presumably some wonky script out there that breaks on the former (or perhaps its POSIX, dunno). I have recently began to appreciate that all this madness that would normally be considered unforgivable code obfuscation in anything but shell scripting, is all an attempt to somehow be portable. In any number of situations I would consider it much preferable to juse choose one particular shell and stick to it, rather than having to do battle with all these minor incompatibilities. Many major shells are very portable to begin with, and in many situation you *REALLY* don't care about some exotic Unix platform that 10 people in the world run, but where bash/zsh/whatever doesn't. Another example of the madness is: http://www.netbsd.org/docs/pkgsrc/makefile.html Check out section 12.3.3. Can anyone claim that it is sensible for it to be this fricking difficult *to print the value of a variable*? Although that last bit has to do with more than the choice of a shell, it highlights perfectly the type of trouble you run into when you try to be portable with the least common denominator. -- / Peter Schuller PGP userID: 0xE9758B7D or 'Peter Schuller <[EMAIL PROTECTED]>' Key retrieval: Send an E-Mail to [EMAIL PROTECTED] E-Mail: [EMAIL PROTECTED] Web: http://www.scode.org
