test3.sh[12]: 426110: not found
It should display:
426110
I tried to copy the file and then try to run vi through the scripts; and edit it; and save it so that a /n will be added at the end (assuming that that is the problem). The file only has one line which is the number of the process id.
It seems simple, but no luck. Any suggestions please....? thank you
It would help to see your whole script. It appears that line 12 of the script test3.sh consists of the line: `cat $pid`
Is that correct?
Also, just running `cat $pid` as a command does not look valid.
Usually that is done to set an environment varilable, thus I tried something similar in Solaris with ksh:
export rp=rpatches
`cat $rp`
ksh: 1): not found
versus
cat $rp
1) Patch 4157095 applied on Fri Apr...
OR
export catrp=`cat $rp`
echo $catrp
1) Patch 4157095 applied on Fri ...
So in your example:
catPid=`cat $pid`
Then you would manipulate $catPid with commands like:
echo ${catPid}
although that seems a bit redundant...
Anyway, the first 11 lines (and the rest) might seem to have a bearing on the issue, but hard to tell without seeing them. Maybe it will be clearer if you show the whole script.
HTH,

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.
