How to suppress "Input is not from a terminal" message?

[Igor]

Hi,

I would like to embed vim code inside bash script.

I have simple text file text_file.txt with content:

aaa

Content sample.sh file:

#!/bin/bash
echo "Start running vim commands inside bash program."
vim +"so dummy.vim" << EOF
   :e text_file.txt
   :s/a/b/
   :x
EOF
echo "End of running run vim commands inside bash program."

Above code opens text_file.txt, replaces letter a with b and saves the file.

When I run sample.sh file from shell: ./sample.sh

The output on terminal is:

Start running vim commands inside bash program.
Vim: Warning: Input is not from a terminal
End of running run vim commands inside bash program.

and script does get executed, so file text_file.txt correctly gets changed to baa

The only little bit annoying thing is the Vim: Warning: Input is not from a terminal message in terminal. How to suppress this message?

Thanks.

Start vim in Ex-mode?

vim +"so dummy.vim" -e << EOF

Bye, Andreas

Have you considered using sed, which was designed for this sort of job.
rather than twisting vim inside out?

Thank you very much for your answers.

I changed line from:

vim +"so dummy.vim" << EOF

to line

vim +"so dummy.vim" -e << EOF

and "annoying" message is suppressed, like I wanted.

Just additional question.

Does -e switch has some negative side effect, like some commands not working or working differently like in standard vim?

I am reading about about "Ex mode" (-e switch) and "Improved Ed mode" (-E switch).
