I saw in this topic that you can add a function in the shell login script instead of an alias if you want to use parameters. However, I placed the following code inside my .cshrc file in the section with aliasses:
function gf()
{
grep -n $1 `find .` | grep -v "can't open"
}
But when I type source .cshrc, I get the error message: Badly placed ()'s. Is the syntax different for a C shell than in a Bash shell? If so, what is the correct syntax?
Unfortunately, you can't define functions in csh, like you can in most other shells. This feature does not exist in csh.
The only alternative is to create a script and place it in a directory on your PATH e.g. ~/bin.
If you are looking for passing only one argument, just put \!$ where you wish your argument to sit.
For example:
If you put alias mygrep grep -i \!$ myfile.txt in ~/.cshrc, and run mygrep mykeyword, csh will run alias mygrep grep -i mykeyword myfile.txt.
See this for more info.
Here is my solution:
#!/bin/csh
if ("$1" == "run") goto $2
echo "Now in default mode"
echo "Calling myself"
csh -f dummy run sub1
csh -f dummy run sub2
exit
sub1:
echo "In sub1"
exit
sub2:
echo "In sub2"
exit
Set the following in your .cshrc or .tcshrc:
alias function '( set argv = ( \!* ) ; source ~/.cshfuncs )'
Define your functions in .cshfuncs:
# Functions for C Shell.
switch ("$1")
case "myfunc":
grep -n "$2" "`find .`" | grep -v "can't open"
exit
case "myfunc2":
echo "Another function."
exit
default:
echo "Function $1 not set."
exit -1
endsw
