[lcd4linux] exec_sample

[Ulf E. <eb...@ti...>]

Hi List,

is there a chance to use the exec_plugin for making a 'cat
/foo/bar.txt',
and is there any example of this available? (Using the cvs-version)

Or is there another possibility to do the same like=20
X1 ... things of 0.9.11 for retrieving external data?

sure:

merlin.ethnet:# lcd4linux -Fvvq -f lcd4linux.conf.sample -ii
Version 0.10.0-RC1 starting

eval> exec('head -1 /etc/passwd', 1000)

thread exec-eaf starting...
forked process 2649 for thread exec-eaf

''

eval> exec('head -1 /etc/passwd', 1000)

'root:x:0:0:root:/root:/bin/bash'

eval>

The first call to exec does not return a result, but returns 
immediately, to not delay execution. Exec's are handled as a background 
process.

Maybe there should be a "generic file parsing" plugin?


bye, Michael
