Conditional Statements in Batch File -


i have written ms dos batch file runs series of commands.

each command invokes program specific parameters. automate this, combined commands.

the structure of batch file shown below:

@echo off if %1 == "b1" ( command 1 command 2 command 3 .... ) else ( command command b command c ) 

i invoke shown below:

test.bat b1 

if pass b1 argument batch file, process series of commands, command 1, command 2, command 3 , on.

similarly, if want execute series of commands mentioned in else section, pass argument:

test.bat abc 

since argument passed batch file not equal b1, start executing else section of batch file. here argument passing (in case, abc) required commands, command a, command b, command c , on parameter.

all works pretty good.

however, issue facing is, if want terminate batch file in between (by pressing ctrl + c), not prompt me option: want terminate batch operation? y/n

for instance, let say, batch file processing series of commands in else section. currently, assume executing command a. if press ctrl + c, instead of prompting me cancel operation cancels execution of command , automatically proceeds command b. if press ctrl + c again, cancels command b , proceeds command c , on.

now, on other hand, if write batch file shown below:

@echo off command command b command c 

and invoke command line as:

test.bat abc 

now, when press ctrl + c while batch file being executed, prompts me cancel batch operation expected.

it appears when add conditional statement in batch file, functionality of ctrl + c modified in way.

how can fix issue?

thanks.

i tried , seemed work expected:

@echo off if "x%1x" == "xb1x" (     echo yes     dir     ... ) else (     echo no not     dir     ... ) 

(where ... repeats previous pair of lines 100 times give time press ctrl-c). did prompt, though break occurred inside if ... else.

so suspect there's unusual commands you're running, , if behaviour red herring. in particular, launching programs, expect ctrl-c gets passed directly program being run instead of batch file launched it.
