Bash script "open terminal and launch command

buntolo · 2012-01-05 23:44:31

I need a script to do this:
launch a terminal, from this change working directory and then launch a command; the terminal have to remain opened after the command execution.
Something like:

$terminal cd $dir && $command

If I open a terminal and I do:

cd $dir && $command

it works

If I do a .sh script with this:

xterm -hold -e cd $dir && $command

or

terminal -H -x cd $dir && $command

when I launch it (the script) it doesn't work.

You can run

xterm -hold -e /path/to/app

the $app being a script

[karol@black ~]$ cat app
#!/bin/bash
cd ~/test/ && ls

That application check if it has already been installed in her actual directory.
In that way the working directory (pwd) will remain the one where the script is and so the application will think it has never been installed and start to install herself again in the directory where the script resides.

What ls stand for?
Not the list command?

Anyway you've got me this idea:
script: it will launch another script which already is in the right directory and this last one will launch terminal with command in.

xterm -hold -e "cd ~/test/ && ls"

works too.

I don't know what $command do you mean, but this will list th ~/test directory.

Why can't you just have

cd $dir

as the first line of your script?

In that way the working directory (pwd) will change only for "cd $dir", then the terminal with the $command will open in the script directory and NOT in "cd $dir"; in this way the application will fail the check and proceed to install in the script-dir.

It works also for me.
With urxvt and xfce4-terminal don't work.
But xterm is too minimalist, is there an advanced terminal based on it?
And I don't unerstand why it doesn't work for xfce4-terminal but for it does for xterm...

man xfce4-terminal:

-H, --hold
Causes the terminal to be kept around after the child command has terminated

-e, --command=command
Execute command inside the terminal

man xterm:

-hold 
Turn on the hold resource, i.e., xterm will not immediately destroy its window when the shell command completes. It will wait until you use the window manager to destroy/kill the window, or if you use the menu entries that send a signal, e.g., HUP or KILL.

-e program [ arguments ... ] 
This option specifies the program (and its command line arguments) to be run in the xterm window. It also sets the window title and icon name to be the basename of the program being executed if neither -T nor -n are given on the command line. This must be the last option on the command line.

What the ...?
Is only my opinion that there aren't differences between:
terminal -H -e "cd $dir && $command"
and
xterm -hold -e "cd $dir && $command"
???

The man page for urxvt explains what to do for execute. hold will work with this:

-e command [arguments]
           Run the command with its command-line arguments in the urxvt window; also sets the window title and icon name to be the basename
           of the program being executed if neither -title (-T) nor -n are given on the command line. If this option is used, it must be
           the last on the command-line. If there is no -e option then the default is to run the program specified by the SHELL environment
           variable or, failing that, sh(1).

           Please note that you must specify a program with arguments. If you want to run shell commands, you have to specify the shell,
           like this:

             urxvt -e sh -c "shell commands"

If urxvt is run w/o 'sh -c', it throws 'urxvt: unable to exec child.' error. Is Terminal printing any errors?

I just tried this in XFCE's terminal and it works fine:

terminal -e ls --hold

Just out of curiosity, what does the '-x' switch do?
