Bash script with command argument not working
Clash Royale CLAN TAG#URR8PPP
Using a bash script ./find_dates. Code in find_dates
grep '^2019/02/01' /pi/home/data/*|sort -t: -k2 > /pi/home/files/data.txt;
I am getting data in the data.txt
However when I run ./find_dates2 2019/02/01. Code in find_dates2:
grep '^$1' /pi/home/data/*|sort -t: -k2 > /pi/home/files/data.txt;
The data.txt is empty.

Simple typo - use double quotes instead of single quotes, otherwise the variable doesn't get expanded.
grep "^$1" /pi/home/data/*|sort -t: -k2 > /pi/home/files/data.txt;
