You can use this "replace_append" script:
Code:
#!/bin/sh
searchkey=$1
shift
sep=$1
shift
replaceval=$1
shift
sed '
# look for the searchkey
  /^'"$searchkey$sep"'/ {
# replace the value
    s#'"$sep"'.*#'"$sep$replaceval"'#
# copy the rest of the file
    :L
    n
    bL
  }
# not found? Append a line
  $a\
'"$searchkey$sep$replaceval"'
' "$@"

And run it with
Code:
./replace_append "puid.7.edx" " = " '"----:00--:----:----:----:----:----:----"' config > config.new

If config.new looks good then copy it back to config.

The script looks for the key, if it matches then it changes the value.
If it does not find the key then it appends a line.

If you have GNU sed then you can add a -i.bak option to sed in the script. Then sed will modify the original file and leave a .bak file. (And you don't need to redirect the output.)
