[SOLVED] Not able to create HERE docs in csh/tcsh

Hello all I I trying to create here docs and I get "No such file or directory" code will be below. When I change shells to bash it works as expected. The shells that I am having a issue with are csh/tcsh, any pointers as to how this works would be helpful. I am thinking it maybe a env type of problem but I am not sure what I should be looking for.

Code:

cat > testtest << EOF

Usually that is done in a shell script:

Code:

#!/bin/bash

cat >testtest <<EOF
data to be put in testtestfile
EOF

Also there is the ability to support indentation to make things a bit clearer:

Code:

#!/bin/bash

cat >testtest6 <<-EOF
     data to be put in testtestfile
     note, leading blanks trimmed
EOF

If the "EOF" is in quotes, then substitutions within the "data to be..." are disabled. Allowing substitutions is nice for generating reports... Things like headers/dates or special text can then be substituted on the fly.

Here documents work the same way for csh, and (I believe) tcsh.

Ok so I tried it in a script and it works as expected on bash but from csh/tcsh I get no such file or directory. Any Ideas why this would happen?

Do you have a .cshrc or other profile file that might be messing things up? Maybe check aliases?

I found the root cause of my issue and it was not being caused by env setting. Thanks to everyone for your input.

So what was the root cause?

There was a script that removed expected directories from /tmp. Fixed the script the issue went away and I can create here files now
