Re: Just want to exclude lines with tabs

Show all headers | View raw

Thanks, everyone.

I just couldn't get Windows command line to let me put a
tab on the line, so I wrote a batch file:

set TAB=	
grep -v "%TAB%" %1.%2  > %1-NoTabs.csv
grep -v "," %1.%2      > %1-NoCmas.tab

Just hit the tab key after "set TAB=".  Not elegant but it works.

grep version:

K:\>grep -V
grep (GNU grep) 2.5.1
