Extract a portion of a command line output

[komathi]

Hi,,

For encrypting password in a data loader i'm using the following code

Code: Select all

java -cp ../lib/EnhencedDataloader.jar com.salesforce.dataloader.security.EncryptionUtil -g "seeddata" > %rootpath%bin\Key.txt
 

and writing the output in the key.txt file. as below,
2014-06-13 16:23:02,859 INFO [main] security.EncryptionUtil main (EncryptionUtil.java:304) - 99b7041393bd3e82

but i need only the value 99b7041393bd3e82 to use in next setp.

How to remove this unwanted text,
In my old version i wont get this extra line in the key.txt file

put the command into a FOR /F command and use a hyphen as a delimiter.
for /f "tokens=4 delims=-" %%G in ('java command here') do echo %%G>file.txt

hi Squashman ,

Thank u , have a single space in front , how to remove this?

Your string might always be 16 characters - but you haven't given much detail.

If so you can take the last 16 characters from the line.

Well if your output is always formatted that way then use a space as the delimiter and if my counting is correct it should be the 8th token then.

+1 That's also a good solution, given a predictable output format

with the hyphen I think it's the 9th token.

Lets hope my Crystal Ball is working correctly today.

for /f "tokens=9 delims= " %%G in ('java -cp ../lib/EnhencedDataloader.jar com.salesforce.dataloader.security.EncryptionUtil -g "seeddata"') do echo %%G>%rootpath%bin\Key.txt
