The difference in behaviour you are seeing results from the difference in the way cmd and bash interpret command lines and pass the resulting arguments to the specified commands.To delete all lines beginning with a <space> in a text file, this command (a) seems correctly composed and (b) works:
sed '/^ .*$/d' filename
but if I use it in a cmd window, the result is that all lines _containing_ a space are deleted, not just those beginning with a space.
In general, and assuming PATHs etc correctly set, should not Cygwin command lines work identically in bash and cmd windows? Is this a problem with sed, with (my) command line syntax above, or with my understanding of what should work when?
C:\>E:\cygwin\bin\echo.exe '/^ .*$/d' / .*$/d
mks ~ $ /cygdrive/e/cygwin/bin/echo.exe '/^ .*$/d' /^ .*$/d
mks ~ $
C:\>E:\cygwin\bin\echo.exe "/^ .*$/d" /^ .*$/d
Regards mks
