i have a variable that has more than one value. i am declaring another variable, which will have the old variable data one by one. i want to use the second variable to hold the track of all the variable it has parsed from the first one. can somebody help me how do i declare and use the second variable?
e.g.
Code:
LIST="A:B C:D E:F"
for VAR in `print $LIST`
do
NAME=`print $VAR | cut -d ":" -f1`
RETURN_VALUE1=`some action`
echo $RETURN_VALUE1
done
i want another variable to keep track of what all LIST variable it has processed and need to display that these values were used

GIT-VAR(1) Git Manual GIT-VAR(1)NAME
git-var - Show a Git logical variable
SYNOPSIS
git var ( -l | <variable> )
DESCRIPTION
Prints a Git logical variable.
OPTIONS -l
Cause the logical variables to be listed. In addition, all the variables of the Git configuration file .git/config are listed as well.
(However, the configuration variables listing functionality is deprecated in favor of git config -l.)
EXAMPLE
$ git var GIT_AUTHOR_IDENT
Eric W. Biederman <ebiederm@lnxi.com> 1121223278 -0600
VARIABLES
GIT_AUTHOR_IDENT
The author of a piece of code.
GIT_COMMITTER_IDENT
The person who put a piece of code into Git.
GIT_EDITOR
Text editor for use by Git commands. The value is meant to be interpreted by the shell when it is used. Examples: ~/bin/vi,
$SOME_ENVIRONMENT_VARIABLE, "C:Program FilesVimgvim.exe" --nofork. The order of preference is the $GIT_EDITOR environment variable,
then core.editor configuration, then $VISUAL, then $EDITOR, and then the default chosen at compile time, which is usually vi.
GIT_PAGER
Text viewer for use by Git commands (e.g., less). The value is meant to be interpreted by the shell. The order of preference is the
$GIT_PAGER environment variable, then core.pager configuration, then $PAGER, and then the default chosen at compile time (usually
less).
