Trimming text files from command line (Windows)

Question

I have a text file which contains several hundred lines e.g.

test.bin:8948549854958

They are all styled like the above file (xxxxxxx.xxx:xxxxxxxxxxxxxx)

Is there any way I could trim all lines e.g. take :xxxxxxxxxxxxxxx of the line, so just to leave xxxxxxx.xxx ?

Answer 1

Trim.bat:

@FOR /F "tokens=1 delims=:" %%G IN (%1) DO @echo %%G

Usage: trim source.txt > destination.txt
