Vim: Warning: Output is not to a terminal

[jeanluca]

Dear Monks

I tried to execute the following command in my perl script:

`vimdiff live/$file test/$file` ;

Which doesn't return the graphical window with the differences, but shows on the command line

Vim: Warning: Output is not to a terminal

and the terminal doesn't respond to anything anymore.

Any suggestions how to fix this ?

Cheers
LuCa

UPDATE: thnx moritz, system works!!

Use diff, not vimdiff.

Alternatively you can use expect to capture output to the terminal.

diff is not the same thing as vimdiff. Is there, for example, no way to start the command in a new shell/terminal ?

I might have misunderstood what you try to accomplish.

Since you've used backticks, I assumed you want to obtain the output from vimdiff - which doesn't work that way, because vim talks to the terminal directly instead of printing to STDOUT. That's why I suggested diff instead, which does print to STDOUT.

If you want to spawn an interactive vim, just use system - works fine here.
