rofi-window shows up and one can type chars into it, but nothing else happens

[rtng]

OS: Debian GNU/Linux 11 (bullseye) x86_64 Kernel: 5.10.0-20-amd64 WM: IceWM 2.1.2 (Linux/x86_64) rofi Version: 1.5.4 ddgr Version: 1.9 Python 3.9.2

1) running '$rofi -lines 5 -eh 3 -show ddgrsearch -modi "ddgrsearch:ddgr_search.sh" ' prompts (german):

• /usr/local/bin/ddgr_search.sh: Zeile 28: [: : Ganzzahliger Ausdruck erwartet.
• /usr/local/bin/ddgr_search.sh: Zeile 33: [: : Ganzzahliger Ausdruck erwartet.

in english that might be:

• /usr/local/bin/ddgr_search.sh: Line 28: [: : Expected integer expression.
• /usr/local/bin/ddgr_search.sh: Line 33: [: : Expected integer expression.

with running this the rofi-window shows up and one can type chars into it, but nothing else happens.

2) running '$bash -x ddgr_search.sh' prompts:

• echo -en '\0prompt\x1fddgr\n' promptddgr
• echo -en '\0delim\x1f;' delim;+ '[' '' -eq 1 ']' ddgr_search.sh: Zeile 28: [: : Ganzzahliger Ausdruck erwartet.
• '[' '' -eq 2 ']' ddgr_search.sh: Zeile 33: [: : Ganzzahliger Ausdruck erwartet.

Thanks for raising the issue.

Replacing, in ddgr_search.sh, the test expressions with double brackets if [[ ... ]] test should fix the issue. I will create the PR shortly.
