Full Discussion: Consecutive spaces within input being converted to single space
Top Forums Shell Programming and Scripting Consecutive spaces within input being converted to single space Post 302134896 by NinersFan on Tuesday 4th of September 2007 08:59:53 AM

That may have been a typo on my part. My program does write to output ok except for the fact that the double space comes out as a single space.

I'm going to ditch using the 'read' command and try using a combination of cat, grep and awk to rip through the file. If I do a :

REC_BUF=`grep '^' $1`

and then output to screen, the 2 spaces appear. Therefore I know it's a 'read' specific feature.
