trying to get fancy with bash conditionals


I got this start up file that I am putting condistionals in to check to see if program is in, if yes then start it, while cutting down on typing letting the system do the most of the work.

it worked with just using this on the dropbox ones so I changed them all to this way and now it is not working at all, so I took it to the terminal to try it in there to see what I get to try and figure this out, so can someone who knows more about the which and how to use it chime in?

the conditionals in question.
Code:
    [[ -x $(which wmix) ]] && $(which wmix) &
        [[ -x $(which wmCalClock) ]] && $(which wmCalClock) &
        [[ -x $(which gkrellm) ]] && $(which gkrellm) &
        [[ -x $(which nm-applet) ]] && $(which nm-applet) &
        [[ -x $(which dropbox)  ]] && $(which dropbox) start &
        [[ -x $(which dropboxd)  ]] && $(which dropboxd) start &
        [[ -x $(which blueberry-tray) ]] && $(which blueberry-tray) &
        [[ -x $(which blueman-applet) ]] &&  $(which blueman-applet) &
        [[ -x $(which qbittorrent) ]] && $(which qbittorrent) &
        [[ -x $(which conky) ]] && 
        [[ -f $HOME/.config/conky/wo-conky-system-lua/WO-conky-system-lua-v3.conkyrc ]] &&
        { $(which conky) -c $HOME/.config/conky/wo-conky-system-lua/WO-conky-system-lua-v3.conkyrc ; } &
        [[ -f $HOME/.config/snitchImages ]] &&  $HOME/.config/snitchImages & 
        [[ -x $(which variety) ]] && $(which variety) &
some of the results, as nothing is starting when I log in, but wmix starts on the cli, and wmCalClock does not because it is not installed.
the ones that are installed start and the ones that are not installed I may be the reson it is not completely working?

which would be a solid yes if the first one was not installed to give a 1 on output, but it is so it should at least start then fail due to the second one not being installed. anyways what is the correct syntax for this?

output to the first three
Code:
[userx@arcomeo ~]$   [[ -x $(which wmix) ]] && $(which wmix) &
[1] 12135
[userx@arcomeo ~]$   [[ -x $(which wmCalClock) ]] && $(which wmCalClock) &
[2] 12140
[userx@arcomeo ~]$ which: no wmCalClock in (/home/userx/bin:/home/userx/.bin:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl)

[2]+  Exit 1                  [[ -x $(which wmCalClock) ]] && $(which wmCalClock)
[userx@arcomeo ~]$  [[ -x $(which gkrellm) ]] && $(which gkrellm) &
[2] 12143

I guess the problem is that

test -x
echo $?

yields 0

I would write the start of your script more or less as follows:

#!/bin/bash
for p in "wmix" "wmCalClock" "gkrellm" ; do
which "$p" >/dev/null && "$p" &
done

good Idea, I created a separate list so it can be easily changed to add or remove apps.
Code:
wmix
wmCalClock
gkrellm
nm-applet
dropbox
dropboxd
blueberry-tray
blueman-applet
qbittorrent
variety
created a test script.
Code:
#!/bin/bash

mapfile -t startapps < ~/startapps

for p in ${startapps[@]} ;
do
	which "$p" >/dev/null && "$p" &
done
logout and in because startscript for session is not working so nothing is getting started, then ran my test script and it started everything in it that is installed.

thanks!

I just need to figure these out now. No Big deal.
Code:
[[ -f $HOME/.config/conky/wo-conky-system-lua/WO-conky-system-lua-v3.conkyrc ]] &&
{ $(which conky) -c $HOME/.config/conky/wo-conky-system-lua/WO-conky-system-lua-v3.conkyrc ; } &

[[ -f $HOME/.config/snitchImages ]] &&  $HOME/.config/snitchImages &
