solution using sed
Here is one way, using sed:

Code:
#!/bin/ksh

pfile="pmonfile.dat"
tmpfile="pmonfile.tmp"

sed -e '1,$s/_stdby$//g' pmonfile.dat > $tmpfile

mv -f $tmpfile $pfile

how's that?

One ksh script coming up:
Code:
#!/bin/ksh
while read line; do
  echo ${line%_stdby}
done <pmonfile.dat >pmonfile.dat.tmp && mv -f pmonfile.dat.tmp pmonfile.dat
