sed 's/patternFrom/patternTo/' file.txt
• "s/" means substitute what follows: this substitution must now be applied to our file, by typing a single line command:
• Commands can be applied by sed only to a selected set of lines. These lines are identified by their progressive number inside the file, starting from line 1.
For example:
sed '2s/patternFrom/patternTo' file.txt
• performs the substitution only on the second line
or
sed '2,$s/patternFrom/patternTo' file.txt
• performs the substitution from line 2 till the last one, identified by the special symbol "$".
Even more
• sed contains an internal buffer, called the hold space. This buffer can be activated by certain commands, for example 'g'. The 'g' command causes the hold space to replace the current input line, so that matches can be repeated on the input line
In your case try to match the all occurrences on all lines with:
sed 's/patternFrom/patternTo/g' file.txt
I think what is not working is the pattern
Make sure the regular expression works, try with
sed 's/jvmRoute="[a-zA-Z0-9-\.]*["]/jvmRoute="VALUE10"/g
