[SOLVED] Assign result of UNIX command to a variable

Issue

I am trying to convert the date format in UNIX, the format is getting converted but unable to assign it to a variable.

DATE=20200520
A=date -d"$DATE" +%Y\-%m\-%d
-bash: -d20200501: command not found

date -d"$DATE" +%Y\-%m\-%d This is properly working, but when assigned to variable it's failing.

I tried assigning using A = $(date -d"$DATE" +%Y\-%m\-%d) symbol as well, still it's not working.

Solution

We have to use $ symbol when assigning the result of another command to a variable.

A=$(date -d"$DATE" +%Y\-%m\-%d)

There is a space in between A and = symbol and $ symbol, that is the reason it failed while using $ symbol
