Pattern: Use of literal =
Issue: -
The shell doesn't care about the = sign in your array assignment because it's not part of a recognized index assignment. Instead, it's considered a literal character and becomes part of an array element's value.
Example of incorrect code:
array=( [index] = value )Here the = was intended to set the index, but the shell will not recognize it when it is surrounded by spaces.
Make sure to remove any spaces around the = when assigning by index, such as in the correct code.
If you wanted the = to be a literal part of the array element, add quotes around it, such as env=( "LC_CTYPE=C" ) or specialChars=( "=" "%" ";" ) .
Example of correct code:
array=( [index]=value )
