How to run csh script from sh script

Question

I was wondering if there is a way to generate a csh script from a sh script. The following is an example of what it is trying to implement:

script1.sh:

#!/bin/sh

source script2

Script2:

#!/bin/csh -f

setenv TEST 1234
set path = /home/user/sandbox

When I run sh script1.sh, I get syntax errors generated from script2 (expected since we are using another Shebang). Is there a way to run script2 through script1?

Answer 1

Instead, source script2run it like:

csh -f script2

Answer 2

Since your use case depends on saving the environment variables specified by the cshscript parameter , try adding this to the beginning script1:

#!/bin/sh

if [ "$csh_executed" -ne 1 ]; then
    csh_executed=1 exec csh -c "source script2;
                                exec /bin/sh \"$0\" \"\$argv\"" "$@"
fi

# rest of script1

csh_executed ​​ 1 , csh script, script2, sh, , script2. exec , , "" . csh_executed csh , , script1 csh.
