Substitution in a file dont work with an Array in filename
Hi.

I´ve a script that should substitude the 8th line in a file called xxx.num6.

The "xxx" is set by an array filled with this command:

Code:
 
j=0
for Par in *.sys ; do
   Par=`echo $Par | sed 's/\(.*\).sys/\1/'` ;
   Par2[$j]="$Par" ; echo "${Par2[$j]}"
   j=$((j + 1));
done

Now i try to implement the substitution with:

Code:
j=0
for dummy in *.sys ; do
   sed '8d' ${Par2[$j]}.num6 > run1.ksh
   sed -e '/ntout/i\tend='$tend_Mges'' run1.ksh > ${Par2[$j]}.num6
   j=$((j + 1))
done

So the substitution works, if i set the Name of the file (e.g. abc.num6) instead of the parameter.
But if I type in "echo ${Par2[$j]}.num6" , the output of the variable is the correct Name. (e.g. abc.num6)

So i think the problem hides into the Syntax of the parameter "${Par2[$j]}.num6" ???

guards

GUARDS(1)						User Contributed Perl Documentation						 GUARDS(1)

NAME

       guards - select from a list of files guarded by conditions

SYNOPSIS

       guards [--prefix=dir] [--path=dir2:dir2:...] [--default=0|1]	   [-v|--invert-match] [--list|--check] [--config=file]        symbol ...

DESCRIPTION

       The script reads a configuration file that may contain so-called guards, file names, and comments, and writes those file names that satisfy
       all guards to standard output. The script takes a list of symbols as its arguments. Each line in the configuration file is processed
       separately. Lines may start with a number of guards. The following guards are defined:

	   +xxx Include the file(s) on this line if the symbol xxx is defined.

	   -xxx Exclude the file(s) on this line if the symbol xxx is defined.

	   +!xxx Include the file(s) on this line if the symbol xxx is not defined.

	   -!xxx Exclude the file(s) on this line if the symbol xxx is not defined.

	   - Exclude this file. Used to avoid spurious --check messages.

       The guards are processed left to right. The last guard that matches determines if the file is included. If no guard is specified, the
       --default setting determines if the file is included.

       If no configuration file is specified, the script reads from standard input.

       The --check option is used to compare the specification file against the file system. If files are referenced in the specification that do
       not exist, or if files are not enlisted in the specification file warnings are printed. The --path option can be used to specify which
       directory or directories to scan.  Multiple directories are separated by a colon (":") character. The --prefix option specifies the
       location of the files.
