I am relative new to shell scripting and sed. I need to substitute a pattern, globably, but I also need to remember (or save) part of the pattern and use it later in the same substitute
command. The saved pattern will be varible, so I need to use a wild card. For example,
input message=trt:GetAudioSourcesRequest/>
and I want to end up with something like
input message=trt:GetAudioSourcesRequest PAUL/GetAudioSourcesRequest/>
but the function string "GetAudioSourcesRequest" will change (in length also) throughtout the
file, so I need a wild card, e.g.
sed -i "s/input message=trt:<wild card in here>/>/input message=trt:<print wild card> PAUL/<print wild card>/>
I have managed to get the following
command to nearly do what I want but it is too rigid. It only stores a 4 syllable pattern so if I have a function name such as GetProfileRequest, this doesn't work
echo "input message=\"trt:GetAudioSourcesRequest\"/>" | sed 's/input message=\"trt:\([A-Z][a-z]*\)\([A-Z][a-z]*\)\([A-Z][a-z]*\)\([A-Z][a-z]*\).*/input message=\"trt:\1\2\3\4\ PAUL\/\1\2\3\4"\/\>/g'
This outputs
input message="trt:GetAudioSourcesRequest PAUL/GetAudioSourcesRequest"/>
Which is ok but when I use GetProfileRequest this doesn't.
I have come accross \W and [^[:alnum:]] or [[:alnum:]] but I don't how to use them
Thanks in advance.
