how to pass numeric array from bash to csh

Question

Firstly, in my defense: I'm only using csh because my group has a lot of legacy csh. We do scientific programming; a lotta folks apparently learned to use csh back in the SunOS/Solaris days, and didn't give up despite the linux/bash transition, and despite the (IMHO obvious) superiority of the latter. Secondly, apologies if this is a FAQ, but I haven't found an answer via SO or googling generally, and I have devoted some effort to both. That being said: I want to drive from bash some legacy csh scripts, as a first step toward [rewriting, removing] the latter. bash->csh works fine for scalar environment variables ('envvars'), in that I can export them from bash and read them from csh as expected. Not arrays, however ... until Chris J. Kiick's answer below! Following example is updated to include Kiick's answer, and the results it produces. Put the following 2 files in the same directory, ... array_writer.sh ``` #!/usr/bin/env bash ### Test writing an array, passing it to csh, and readi…

Accepted Answer

I'm not familiar with arrays in csh, but exporting seems easy enough:

in bash:

```
bdom=${BDOM[*]} mday=${MDAY[*]} ${PARTNER_FP}
```

You don't need the "env" command, bash has that built in.

To make $bdom into a list of words, instead of a single string, use (). in csh:

```
set bdom_array = ( $bdom )
```
