Subject: fix(bkgpslog):Apply shellcheck corrections
X-Git-Url: https://zdv2.bktei.com/gitweb/EVA-2020-02.git/commitdiff_plain/0b3dde0530513a3027de7d5f81a4386a118fce5c?ds=sidebyside

fix(bkgpslog):Apply shellcheck corrections

- Misuse of array and string ("$@" instead of "$*" in error messages)
- Incorrect comparison ( [ "" -eq "" ] instead of [ "" = "" ] )
- Missing quotation marks around string variable.
