shouldn't the output come as
rather, its coming as :
no. this is because its using the default characters for $IFS(internal field separator) which is white space. set IFS='\n' prior to your loop and you should get what you expect. I would wrap your variable in double quotes though.
If I have a data file containing entries like-> abc abc:123
and I use a for loop:
for I in `cat data-file`
do
echo $I
done
the output would contain 2 lines -> abc.... and abc:123
but I want it to be on only one line. How can I do this?

I have a script to do a couple simple but repetitive commands on files that are provided to us. One of the things is to get rid of the line feeds. This is the section that is causing problems, i even cut this section into its own file to make sure nothing else was affecting it.

gzexe
GZEXE(1) General Commands Manual GZEXE(1)NAME
gzexe - compress executable files in place
SYNOPSIS
gzexe [ name ... ]
DESCRIPTION
The gzexe utility allows you to compress executables in place and have them automatically uncompress and execute when you run them (at a
penalty in performance). For example if you execute ``gzexe /bin/cat'' it will create the following two files:
-r-xr-xr-x 1 root bin 9644 Feb 11 11:16 /bin/cat
-r-xr-xr-x 1 bin bin 24576 Nov 23 13:21 /bin/cat~
/bin/cat~ is the original file and /bin/cat is the self-uncompressing executable file. You can remove /bin/cat~ once you are sure that
/bin/cat works properly.
This utility is most useful on systems with very small disks.
OPTIONS -d Decompress the given executables instead of compressing them.
SEE ALSO gzip(1), znew(1), zmore(1), zcmp(1), zforce(1)CAVEATS
The compressed executable is a shell script. This may create some security holes. In particular, the compressed executable relies on the
PATH environment variable to find gzip and some other utilities (tail, chmod, ln, sleep).
BUGS
gzexe attempts to retain the original file attributes on the compressed executable, but you may have to fix them manually in some cases,
using chmod or chown.
