I am trying to check for a single period '.' in a shell variable.
$ I=. $ echo $I . $ if [[ "$I" -eq '.' ]]; then echo true; fi -bash: [[: .: syntax error: operand expected (error token is ".")
All other variants of this construct, with and without escape characters, single and double quote combinations, that I can think of all give exactly the same error.
How does one check to see for this in a bash script?
