在bash脚本中执行tcsh命令

Question

In a bash script I need to execute this tcsh command. This command works fine in a tcsh command prompt but not in my bash script.

eval `/app/modules/0/bin/modulecmd tcsh $variable`

I have tried several things like adding

/usr/bin/tcsh -c eval `/app/modules/0/bin/modulecmd tcsh $variable`

but then it says: No such file or directory.

Edit: current code:

# hook for some commands

echo 'To be sure the version that are loading exist for your platform plase use: "module aplikation load/version" instead of "module load application". A check will then be done.'
cmd=$(basename "$0") # it givs error here if i start with: tcsh -v xmodule load firefox/3.6.13     
var1=$(echo "$@" | awk '{print $2}' | cut -f1 -d"/") # Gets the application name and put it into var1
var2=$(echo "$@" | grep -o '[^/]*$')  # Gets version name and put it into var2 

if [[ $cmd = "xmodule" ]]
        then
#First if statement: checking if a spesific version of an apllication is requested.
        if  [[ ${@} =~ .*/.* && ${@} =~ ((^)|([ ]))load(($)|([ ])) ]]
        then
           if find /app/$var1 -noleaf -maxdepth 1 -type l -o -type d | grep $var2; then #matching version to symlink or dir in /app/appname/
           echo "$@"
           tcsh -c 'eval `/app/modules/0/bin/modulecmd tcsh $@`'  #execute the module command as normal if version exist
           exit $?
        else
           echo "Could not find $var1 or $var2, one of these things happend:"
           echo "$var1 was misspelled"
           echo "$var2 was misspelled"
           echo "version does exist as a module but not for your platform (see module avail $var1). Printing a list of suported versions:"
                ls /app/$var1/
           echo "exiting: please rety again"
           exit $?
        fi
fi
# Next check. Checking if default module version is loaded
fi
exit

EDIT again:

Environmental variables are actually set, but not for the user who runs the script

See man tcsh . You must quote the eval ... command:

tcsh -c "eval \`/app/modules/0/bin/modulecmd tcsh $variable\`"

Otherwise bash will interpret the backticks command.
