Open a terminal via gnome-terminal then execute command, error : "failed to execute child process"" [closed]

Question

Via a bash command, I want open a terminal and, from the new terminal, execute a simple bash command.

I tried:

gnome-terminal -- "/bin/bash -c ls"

But I got this error:

I don't understand the error and I cannot find an example anywhere for help.

Use the -e option. It's taking that command as the name of a program to run, not a shell command to execute. – Patroclus

SO is for programming questions, not questions about using or configuring Linux and its applications. SuperUser.com or unix.stackexchange.com would be better places for questions like this. – Patroclus

-e arg is deprecied :/ ('Option “-e” is deprecated and might be removed in a later version of gnome-terminal.'). Nothing work when I use -e option, I get just the "deprecated" message – Misfeasance

gnome-terminal -- /bin/bash -c ls. No quotes. – Susceptive

nothing happen when I don't use quotes, no error, no new terminal, nothing – Misfeasance

Probably because it's exiting immediately. Try instead, say, gnome-terminal -- /bin/bash -c 'ls; sleep 3' – Susceptive

BTW, this has already been asked and answered here before. Give me a minute to find the duplicate to close the question... – Susceptive

hannn your right ! its work ! is there a way for 'keep' alive the new terminal after the command ? – Misfeasance

Give it any command that waits indefinitely without exit. – Susceptive

ok =) thank you a lot ! – Misfeasance

Ahh -- the other question I was thinking about was #48237037, but while the answer covers some similar ground, it's not quite a duplicate. – Susceptive

Answer 1

The quotes are telling the terminal to run an executable in /bin called bash -c ls (with the spaces as part of its name!). There exists no such executable.

Take them out:

gnome-terminal -- /bin/bash -c ls

...or, to actually make something stay open until the user provides input...

gnome-terminal -- /bin/bash -c 'ls; read'

thank you :) as I ask from comment , is there a way for keep alive the new terminal regardless the command executed ? – Misfeasance

On a GNU system, you could run sleep infinity as the final command. More portably, though, I'd expect that sleep $(( 60 * 60 * 24 * 365 )) (to sleep for a year) would probably be good enough. – Susceptive

You can try gnome-terminal -- /bin/bash -c 'ls;exec /bin/bash' – Laos
