Unable to display correctly the contents of a file without a line feed
I am using AIX and ksh.
I need to display the contents of a file that has a pid (process id). Because the file is open, it doesn't have the line feed or new line, so for some reason if I do this:
`cat $pid` , where $pid is the name of the fully qualified file, it displays
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

pslist

PSLIST(1)						    BSD General Commands Manual 						 PSLIST(1)

NAME

     pslist -- control processes and their descendants

SYNOPSIS

     pslist [pid/name...]
     pslist -h | --help
     pslist -v | --version

     rkill [-SIG] pid/name...

     rrenice [+/-]pri pid/name...

DESCRIPTION

     The pslist utility examines the list of current processes to find a specified process and all its descendants.  A process may be specified
     either by name or by process ID.  If no arguments are given, pslist displays a list of the whole process tree.  For each process specified on
     the command line, pslist outputs a line containing the process ID, the command name, and the PIDs of all the descendants (and their descen-
     dants, etc.).

     When invoked as rkill, this utility does not display information about the processes, but sends them all a signal instead.  If not specified
     on the command line, a terminate (SIGTERM) signal is sent.

     When invoked as rrenice, this utility does not display information about the processes, but attempts to set their nice value instead.

RETURN VALUES

     The pslist utility exits 0 on success, and >0 if an error occurs.

SEE ALSO

     pgrep(1), pkill(1)

HISTORY

     The pslist utility was written by Peter Pentchev in 2000.
