term_args in config file? (For scrollback buffer) #132

Closed darkpixel closed 3 years ago

darkpixel commented 4 years ago

It looks like clusterssh fires up instances of xterm to display the data. Per the xterm man page, I can increase the scrollback buffer by passing -sl 50000.

And it looks like it works when I run: cssh --term-args="-sl 50000" mycluster

But if I add term_args=-sl 10000 to the .clusterssh/config file and try to run cssh mycluster (because I never remmber to add the term-args flag until it's too late), I get Unknown configuration parameters: term_args.

Am I doing it wrong, or is this unsupported?

Looks like in the config file, you need to specify "terminal_args" instead of "term_args"

.clusterssh/config contains:

terminal=xterm
terminal_args="-sl 50000"

If I launch xterm manually via xterm -sl 50000 it runs normally, but through clusterssh I get this:

Cannot open pipe for reading when talking to --redacted-- : Interrupted system call
xterm: bad command line option "-sl 50000"

Oops--I'm an idiot. Don't quote terminal_args:

terminal=xterm
terminal_args=-sl 50000

Fixed--thanks for the help @jfbauer432
