How can I use spaces in systemd command line arguments?

Question

I have a systemd unit with spaces in an argument

ExecStart=command --argument=\"text text\"

It seems that systemd does not recognize the do

Answer 1

Systemd service file supports this

Environment="TEST=one word"
Environment="TEST2=second word"

ExecStartPre=-/bin/echo start pre
ExecStartPre=/bin/echo start pre mandatory
ExecStart=/bin/echo started : ${TEST} $TEST2
ExecStartPost=-/bin/echo start post
ExecStartPost=/bin/echo start post mandatory
ExecStop=/bin/echo stop
ExecStopPost=-/bin/echo stop post
ExecStopPost=/bin/echo stop post mandatory
ExecReload=/bin/echo reload

log :

Mar 09 21:39:47 gitlab-runner-1 echo[30286]: start pre
Mar 09 21:39:47 gitlab-runner-1 echo[30288]: start pre mandatory
Mar 09 21:39:47 gitlab-runner-1 echo[30295]: started : one word second word
Mar 09 21:39:47 gitlab-runner-1 echo[30296]: start post
Mar 09 21:39:47 gitlab-runner-1 echo[30297]: start post mandatory
Mar 09 21:39:47 gitlab-runner-1 echo[30298]: stop
Mar 09 21:39:47 gitlab-runner-1 echo[30299]: stop post
Mar 09 21:39:47 gitlab-runner-1 echo[30300]: stop post mandatory

But you may actually want to set this if the app needs to read the whole string as 2 arguments, each argument between "" (not tested)

ExecStart=command "$ARG1" "$ARG2"
