Trim issue

scorpio · #1 (**permalink**) 04-28-2008

Hi All,

I am using trim in my code..

ID_SA_SOURCE="`echo "$data" | cut -c17-34 | tr -s " "`"
ID_SA_DEST="`echo "$data" | cut -c35-52 | tr -s " "`"
echo"$ID_SA_SOURCE";"$ID_SA_DEST";
the output is

0608166896; 3001339; contains one whitespace between the two ..how can i remove that single white space ?

Thnks

tr -d instead of tr -s maybe? It's not really clear from your question where exactly that space is coming from.

agreed, it's very unclear what you're wanting to do..2 things however,
tr is "translate charachters" not trim!
the format you're using is not correct, you don't have double quotes formatted correctly."actually you don't have double-quotes.

Code:

tr -s " "`"  ## 3 quotes, not 4!
you also might want to use the ascii equiv to "`" char
or 
tr -s " " "\`"

That's because that's inside backticks which are inside double quotes. The final double quote goes with the starting quote right before the starting backquote.
