Fciv - integration check
The script assumes the md5 hash value is contained in a .md5 file and the naming convention appears as so:
:md5 for /f %%f in ('dir "*.md5" /s/b') do ( set file=%%f for /f %%a in ('type "!file!"') do ( set md5=%%a set md5=!md5:"=! set file=!file:~,-4! for /f "skip=3" %%b in ('fciv "!file!"') do ( if [!md5!]==[%%b] ( echo PASS: !file! echo MD5: !md5! vs. %%b echo. ) else ( echo !!! FAIL: !file! echo MD5: !md5! vs. %%b ) ) ) )
IF and ELSE
- The else needs to be on the same "line" as the if. From IF /? 'The ELSE clause must occur on the same line as the command after the IF.'
if "zz"=="TRUE" ( copy /a zz + /a ee=/a zz ) else ( copy /a e + /a %TMP%=/a e )
- Environment variables in batch files are expanded when a line is parsed.
In the case of blocks delimited by parentheses (as your if defined) the whole block counts as a "line" or command and it is read once. This means that all occurrences of %FOO% are replaced by their values before the block is run. Therefore %FOO% will be replaced by nothing as it was not set.
To solve this you can enable delayed expansion:
Delayed expansion causes variables delimited by exclamation marks (!) to be evaluated on execution instead of parsing which will ensure the correct behavior in our case:
if not defined BAR ( set FOO=1 echo Foo: !FOO! )
