Pattern: Use of space around =
Issue: -
Parameters to export, declare, local, typeset and readonly may not have spaces around the = or += operator. This is the same as for regular variable assignments:
export var = value # Invalid: spaces around =
export var =value # Invalid: space before =
export var= value # Invalid: space after =
export var=value # Valid
This is because each individual argument to these commands is interpreted as a string in the format name=value. By adding spaces, you are instead passing the three strings var, =, value, none of which follow this format.
Example of incorrect code:
export LC_ALL = "POSIX"Example of correct code:
export LC_ALL="POSIX"
