or
eval will force the expansion of $var but not the one which is \ protected
so the finale commande after eval should look like
echo "cp $SOURCE_NAME1 $TARGET_NAME1"
Note that this would suppose that you have already setup the 2 other variables
... which does not currently appear in your code
You could just copy dir
If you want to move them and rename them at the same time, please give us some clue about how you want them to be renamed
We need to scramble data in a number of ASCII files. Some of these files are extremely large (1.2 GB). By scrambling, I mean that we need to substitute certain strings, which number around 400, with scrambled strings. An example has been given below
If "London" occurs in the file, then it... (2 Replies)

shift
shift(1) User Commands shift(1)NAME
shift - shell built-in function to traverse either a shell's argument list or a list of field-separated words
SYNOPSIS
sh
shift [n]
csh
shift [variable]
ksh
* shift [n]
DESCRIPTION
sh
The positional parameters from $n+1 ... are renamed $1 ... . If n is not given, it is assumed to be 1.
csh
The components of argv, or variable, if supplied, are shifted to the left, discarding the first component. It is an error for the variable
not to be set or to have a null value.
ksh
The positional parameters from $n+1 $n+1 ... are renamed $1 ..., default n is 1. The parameter n can be any arithmetic expression that
evaluates to a non-negative number less than or equal to $#.
On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:
1. Variable assignment lists preceding the command remain in effect when the command completes.
2. I/O redirections are processed after variable assignments.
3. Errors cause a script that contains them to abort.
4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari-
able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation are not
performed.
