Hammer & Screwdriver Resolving a parameter which is passed as parameter
Hi,
I have the following files.
->cat scr.sh
Code:
export TMP_DIR=/home/user/folder1
export TMP_DIR_2=/home/user/folder2
while read line
do
cat "$line"
done<file_list.dat

------------------------
-> cat file_list.dat
Code:
$TMP_DIR/file1.txt
$TMP_DIR_2/file2.txt

---------------------------
-> cat /home/user/folder1/file1.txt
Code:
This is data from file1

---------------------------
-> cat /home/user/folder2/file2.txt
Code:
This is data from file2

-------------------------------
**************************************************
In the above code when I execute the scr.sh file, variable $TMP_DIR and $TMP_DIR_2 are not getting resolved. instead the error it shows file not available:$TMP_DIR/file1.txt .
My objective is to get the content of file1 and file2 inside scr.sh for further processing.
Could someone please help me on this.

Thanks in advance
TSB

lzdiff

XZDIFF(1)							     XZ Utils								 XZDIFF(1)

NAME

       xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files

SYNOPSIS

       xzcmp [cmp_options] file1 [file2]
       xzdiff [diff_options] file1 [file2]
       lzcmp [cmp_options] file1 [file2]
       lzdiff [diff_options] file1 [file2]

DESCRIPTION

       xzcmp  and  xdiff invoke cmp(1) or diff(1) on files compressed with xz(1), lzma(1), gzip(1), or bzip2(1).  All options specified are passed
       directly to cmp or diff.  If only one file is specified, then the files compared are file1 (which must have a suffix of	a  supported  com-
       pression  format)  and  file1 from which the compression format suffix has been stripped.  If two files are specified, then they are uncom-
       pressed if necessary and fed to cmp(1) or diff(1).  The exit status from cmp or diff is preserved.

       The names lzcmp and lzdiff are provided for backward compatibility with LZMA Utils.

SEE ALSO

       cmp(1), diff(1), xz(1), gzip(1), bzip2(1), zdiff(1)

BUGS

       Messages from the cmp(1) or diff(1) programs refer to temporary filenames instead of those specified.
