Hello,
I have following variables in my config:
SetEnv XTERM_log1 "`date +%Y%m%d_%H%M%S`"
SetEnv XTERM_log2 "`hostname -a |tr -d ' '`"
SetEnv XTERM_log3 "`echo $[DISPLAY] |sed 's/\..*//'`"
and if I open a XTermand do a
env |grep XTERM
I get
XTERM_log1=`date +%Y%m%d_%H%M%S`
XTERM_log2=`hostname -a |tr -d " "`
XTERM_log3=`echo ":1.0" |sed "s/..*//"`
My first question now is: Why are the Variables are NOT expanded?
Now, if I continue with
SetEnv XTERM_log "-l -lf
$[HOME]/log/xterm/$[XTERM_log1]-$[XTERM_log2]$[XTERM_log3].log"
it looks like
XTERM_log=-l -lf /home/michelle.konzack/log/xterm/`date
+%Y%m%d_%H%M%S`-`hostname -a |tr -d " "``echo ":1.0" |sed "s/..*//"`.log
Why is this? If I se such things, I expect, the varianbles are expanded
as they are used, which mean, if for example the hostname has changed,
it use automaticaly the NEW one.
OK I use the Variable $[XTERM_log] form a ButtonMenu as
exec xterm $[XTERM_log]
The string should produce something like
~/log/xterm/20060930_112712-devel.private:1.log
but it does not. $[XTERM_log3] is alwas missing. So
SetEnv XTERM_log3 "`echo $[DISPLAY] |sed s/\..*//`"
is not working, but on the commandline as
echo $[DISPLAY] |sed s/\..*//
OK, it seems the Shell is eating my \ and I changed it to
SetEnv XTERM_log3 "`echo $[DISPLAY] |sed 's/\\..*//'`"
which output
XTERM_log=-l -lf /home/michelle.konzack/log/xterm/`date
+%Y%m%d_%H%M%S`-`hostname -a |tr -d " "``echo ":1.0" |sed "s/..*//"`.log
OK more backslashes again:
SetEnv XTERM_log3 "`echo $[DISPLAY] |sed 's/\\\\..*//'`"
and now it output
XTERM_log=-l -lf /home/michelle.konzack/log/xterm/`date
+%Y%m%d_%H%M%S`-`hostname -a |tr -d " "``echo ":1.0" |sed "s/\..*//"`.log
but it fails too.
It seems this is a Bug in fvwm?
I need this construct, since I do not want to have a DISPLAY of ":X.Y".
