Batch for configuration/data upgrades

along these lines, not tested: @echo off & setlocal fc c:\dahdah p:\dahdah > nul if %errorlevel% gtr 0 ( copy /y p:\dahdah c:\dahdah ) ::----- end ----- but looking at it, why not just do a straight copy, after all, unless files are great-big, who cares?

nbrane, OP is using DOS 6x. No setlocal; no gtr. fc bla bla > nul if errorlevel 1 copy bla ===================================== Helping others achieve escape felicity M2

Yeah, the OP might as well just copy file straight out. After all, FC pulls it over the network, and if you decide to perform the copy, you're pulling the file a second time.

tvc March 30, 2010 at 04:15:17

Yes, but a copy should only be made if a copy is needed. If FC works on DOS6.22, I'm with M2 on this one

R2 is right, as usual.FC does a read AND compares the two. ===================================== Helping others achieve escape felicity M2

Hi. Thanks for replies, i'll try M2 solution tomorrow. Reason why I want to compare files is, because if there are differences (unauthorized modification of local files, or updated files on network) I want to perform restart with correct files.

Hi again. Well... I'm still stuck. I did test batch with following content, but can't get errorlevel out of it. test.bat: FC CONFIG1.SYS CONFIGX.SYS ECHO KO ERRORLEVEL=%ERRORLEVEL% IF ERRORLEVEL 1 GOTO DOUPDATE GOTO NOUPDATE :DOUPDATE ECHO UPDATE AND RESET PAUSE EXIT :NOUPDATE ECHO NOUPDATE PAUSE results into: ..... 0000039E: 68 0D 0000039F: 6C 0A FC: CONFIG1.SYS longer than CONFIGX.SYS KO ERRORLEVEL= NOUPDATE Press any key to continue . . .

"ECHO KO ERRORLEVEL=%ERRORLEVEL%" I don't know why that line fails to put out a number. Maybe post the rest of the bat. ===================================== Helping others achieve escape felicity M2

It's whole bat (only first row is missing "ECHO OFF" ). I'm testing it in Vmware virtual machine, i'll try it on real machine tomorrow.

FC CONFIG1.SYS CONFIGX.SYS ECHO KO ERRORLEVEL=%ERRORLEVEL% IF ERRORLEVEL 1 GOTO DOUPDATE You are checking the errorlevel of ECHO, not the errorlevel of FC Errorlevel-checking can only be done on the last command executed

old dos won't echo a %errorlevel%, only respond to it. quite retarded, in my book. even the friggin response is limited to "greater than", so you have to do a lot of sucky testing to make sure you got it right. @tvc, good point too: always grab errorlevel immediately or it will be disrupted by the next command.

so. I did the test on real HW and result is same as in VMware. I made another test bat, but again - not working... tets2.bat results into 0000 ECHO OFF FC CONFIG1.SYS CONFIGX.SYS IF ERRORLEVEL 5 GOTO 5555 IF ERRORLEVEL 4 GOTO 4444 IF ERRORLEVEL 3 GOTO 3333 IF ERRORLEVEL 2 GOTO 2222 IF ERRORLEVEL 1 GOTO 1111 IF ERRORLEVEL 0 GOTO 0000 :5555 echo 5555 goto blargh :4444 echo 4444 goto blargh :3333 echo 3333 goto blargh :2222 echo 2222 goto blargh :1111 echo 1111 goto blargh :0000 echo 0000 goto blargh :blargh PAUSE also this one is not working: ::EL.BAT v2.15 (283 bytes) ::Displays errorlevel set by last program run ::by: Vernon Frazee 12/94 - Last mod: 03/97 ::http://www.vfrazee.com @echo off FC CONFIG1.SYS CONFIGX.SYS set a=Errorlevel|set b=|set c=for %%_ in (0 1 2 %c%) do if %a% %%_00 set d=%%_ if not %a% 200 set b=6 7 8 9 %c% 3 4 5 %b%) do if %a% %d%%%_0 set d=%d%%%_ if not %a% 250 set b=6 7 8 9 %c% 3 4 5 %b%) do if %a% %d%%%_ set d=%d%%%_ set a=|set b=|set c=|set d=|echo %d%

I didn't find edit button so here is next post ... EDIT: omg I'm blind found it now .... I have been probably thinking about solution too much :) I can get errorlevel 1 this way "fc configx.sys" (FC: Insufficient number of file specifications) so errorlevels do work. maybe under DOS it should return 0 even if files are different? but then I also need to do the check differently. so finally this seems to be working @echo off FC CONFIG1.SYS CONFIGX.SYS > err.txt FIND "no" err.txt IF ERRORLEVEL 1 GOTO DOUPDATE GOTO NOUPDATE :DOUPDATE ECHO UPDATE AND RESET PAUSE :NOUPDATE ECHO NOUPDATE PAUSE

maybe try to boil it down to bare nails. do something really "dumb" to kick error, then see what hapns: @echo off & setlocal type fartblog.yek if errorlevel 1 echo levelone if errorlevel 2 echo leveltwo? if errorlevel 0 echo you actually have a file called fartblob.yek? ::---- then, assuming you don't, you should see "levelone". then run your fc and immediately discharge the errorlevel (and, make SURE the confits are, indeed, different!): fc config.sys configx.sys if errorlevel 1 goto lev1 if errorlevel 0 goto lev0 :lev1 echo different goto :xit :lev0 echo same :xit ::------ ooops!! damn!! sorry you are indeed correct, i made a trip to the dungeon to check the dinosaur, and fc did not report the errorlevel on a file mismatch. good idea using the find!

tvc April 2, 2010 at 07:55:04

Of course, when checking errorlevel, the first question you should ask yourself is, do you KNOW that this command/script returns an exitcode ? Then, WHAT exitcodes does it return for what cases ?

I'm going to boot in DOS and check. ===================================== Helping others achieve escape felicity M2

You're right; NG in DOS. It's a bit disconcerting to realize how limited DOS is. But refreshing to get a snappy interface, after using CMD prompt, which is like jogging in wet cement. ===================================== Helping others achieve escape felicity M2
