Xdialog scripting question - progress bar
« on: December 18, 2010, 08:30:59 PM »
...not beer or gold bar.  This a thermometer, speedometer bar showing the progress of something.   Keeps one entertained while BigSlowProgram loads.

How do I make it the "front-end" while BigSlowProgram loads ?
There is no RUN command in BASH.   I tried the background ampersand ruse, but Opera (as example) will not run (pun) in background 'mode'.

Any Guroo solutions ? :)        ( Please - only TinyCore capable.  No PHP etc. )

There is no RUN command in BASH.

There is 'exec', but don't use it indiscriminately.

BASH:
Xdialog --progressbar.....10...9...8...7....6...5
exec BigSlowProgram :(

Results: 
Xdialog completes countdown from 10 to zero.
BigSlowProgram loads ( you are watching a blank screen) and runs. :P

Desired:
BigSlowProgram loads WHILE you watch Xdialog count down.

exec is not exactly a "run in background command" but is for replacing the current process with another.

hmmmm...  I guess I'm in deep water.  I hoped for something simple that could be added to the wbar exec command line.  

Using Opera as my BigSlowExample, It seems I need another script to SET all values in background (matching user TC's foreground) so that Opera will run.  
Opera attempts it's first-time-run processes ( like a new user ).

Thanks for your help.

Opera is an X client, and cannot run outside of a logged-in X server with proper authentication..
Any logged in X user should be able to 'opera &'.

One reason why this could happen is when no preexisting profile dir is used.

Got it ! :)

script1 appears:
/usr/local/bin/opera -nomail -nolirc -personaldir /home/tc/.opera/
exit

# tinypoodle was right-on to -personaldir
# Opera documentation  ::)   no comment!

script2 appears:
script1 &       #launch Opera
xdialog progress bar... 10.. 9... 8...
exit


wbar
Changed Opera entry to read exec /user/tc/script2

Later I'll add a 'single-instance' check to allow only 1 Opera.

Not sure if '-personaldir' would work, but '-pd' certainly does   ;)
