vim is an acronym for vi improved. Works just like ye olde vi, just has some perks added (such as multiple undo and command recall). As for your problem with the shell script, I can't quite make out the difference between bash and "a real/true" shell (what's the difference for you anyways? A certain version?). On Linux, using bash and AT&T Korn Shell (test.sh was created on Windows XP using Notepad): Code:
> cat test.sh touch Apple echo me thinks bash is not so good > /bin/bash test.sh touch: cannot touch `Apple\r': No such file or directory me thinks bash is not so good > /usr/bin/ksh test.sh touch: cannot touch `Apple\r': No such file or directory me thinks bash is not so good On HP-UX, again using the same shells: Code:
$ /usr/local/bin/bash test.sh me thinks bash is not so good $ ls -b Apple* Apple\015 $ rm Apple* $ /usr/bin/ksh test.sh me thinks bash is not so good $ ls -b Apple* Apple\015 Both AT&Ts Korn Shell and bash are fully (to my knowledge) POSIX compatible shells, based on the original Korn shell. The original Bourne Shell isn't POSIX compatible, neither is the C Shell (and it's successors). As for bash being a free shell: it's not the only one. AT&Ts Korn Shell has public available source code since 2000, and most Linux distributions have since added it to their repositories (including Cygwin). And then there's ash, dash, zsh, ... |
