- I am switching over from the csh shell to the GNU bash shell, and am
- having some troubles getting equivalent alias commands between the two.
-
- Specifically, I have two directory related aliases in csh like this:
-
- alias dir='ls -aFglNqsT \!* | more'
- alias ls='ls -CFq \!* | more'
-
- My understanding is that you cannot put command line arguments into
- bash aliases (right?), so I wrote the following two bash functions:
-
- dir () { ls -aFglNqsT $1 | more ; }
- ls () { ls -CFq $1 | more ; }
-
- based of the example of functions given in the man page (btw/why the
- semicolon at the end?). THESE FUNCTIONS DO NOT WORK. If I rename
- the ls function to foo, then they both end up working correctly!
- Otherwise, I get some error message about fork processes. Evidently,
- bash doesn't like you "functioning" UNIX commands? I want to do an
- ls with the -CFq arguements almost all the time just by typing "ls".
- Is this somehow not possible in bash?
-
- Another question I had was in converting the following alias:
-
- alias whereis "find ~ -name '\!*' -print | more"
-
- the function I wrote was:
-
- whereis() { find ~ -name $1 -print | more }
-
- For some reason, this function won't work with the single quotes just
- after the -name option and before the -print function (why?). As it
- is now, it just works unreliably. In csh, this is supposed to give a
- list of all files matching a specific pattern, for example
-
- whereis *.ps
-
- would list the full pathname of any file that ended in ".ps".
-
- This function in the bash shell, will only list one, or maybe more,
- but usually not all of the files that end in ".ps". Why not?
-
- befuddled,
