Sourcing .cshrc (C shell) environment variables to bash
I have tried with the following:
Code:
csh -c 'source ~/.cshrc; exec bash' # works perfectly
(cat ~/.cshrc; echo exec bash) | csh # not working


And, using sed, I successfully retrieved the environment variables from ~/.cshrc
Code:
sed -rn 's/setenv\s+(\S+)\s+(.*)$/export \1=\2/p' ~/.cshrc

but now stuck-up in sourcing it to the bash environment, where the below solutions do not work Smilie
Code:
sed -rn 's/setenv\s+(\S+)\s+(.*)$/export \1=\2/p' ~/.cshrc | bash
source /dev/stdin < <(sed -rn 's/setenv\s+(\S+)\s+(.*)$/export \1=\2/p' ~/.cshrc)

You are over complicating things. Why not just write the variables out to a temporary file and source that temporary file?

Even simpler, just write a .myownfile containing the variables and source that file.

.cshrc is automatically sourced
Code:
csh -c 'exec bash'

You need eval
Code:
eval $(
sed -rn 's/^\s*setenv\s+(\S+)\s+/export \1=/p' ~/.cshrc
)

...being it's just a more complicated version of what he did in one parameter, why? What's your goal here?

Using grep move all setenv statements into, say, .setenv. Next, add the following to your .bashrc:
Code:
setenv() { export $1="$2"}
. ~/.setenv

Edit your .cshrc file and comment out or delete your setenv statements, and add
Code:
source ~/.setenv

(or whatever the correct syntax is).

From now on keep all your environment definitions in .setenv and both csh and bash will be able to use them.
