A variable is including the Carriage Return char...
Hi all,

I'm reading a file with this layout:

First_Col Second_Col

The Second_Col has values as 1000, -1, 10, 43...

While reading the file I'm getting the second column value with awk command, but it is including the CR control char.

Code:
do
   item_saved=`echo $b | awk '{print $1}'`   #Get value ITEM_SAVED
   valu_saved=`echo $b | awk '{print $2}'`   #Get value VALU_SAVED
   valu_saved=`expr $valu_saved`
   .....

It is affecting my output in a new flat file (after validations).

Is there a way to remove this CR char from the string? converted to number using
Code:
`expr $valu_saved`

?

Thak you!

GIT-COLUMN(1)							    Git Manual							     GIT-COLUMN(1)

NAME

       git-column - Display data in columns

SYNOPSIS

       git column [--command=<name>] [--[raw-]mode=<mode>] [--width=<width>]
		    [--indent=<string>] [--nl=<string>] [--padding=<n>]

DESCRIPTION

       This command formats its input into multiple columns.

OPTIONS

       --command=<name>
	   Look up layout mode using configuration variable column.<name> and column.ui.

       --mode=<mode>
	   Specify layout mode. See configuration variable column.ui for option syntax.

       --raw-mode=<n>
	   Same as --mode but take mode encoded as a number. This is mainly used by other commands that have already parsed layout mode.

       --width=<width>
	   Specify the terminal width. By default git column will detect the terminal width, or fall back to 80 if it is unable to do so.

       --indent=<string>
	   String to be printed at the beginning of each line.

       --nl=<N>
	   String to be printed at the end of each line, including newline character.

       --padding=<N>
	   The number of spaces between columns. One space by default.
