Create file - pipe to output

At first I must say that my English is not very well. I have to do my task from studies and I have a problem. I have to make file with version in the proper catalog. Information are in text file for example:

com.amazonaws.services.cloudwatch;version=1.1.5

This is a direction to catalog, in which I have to create file:

1.1.5

Now I write:

egrep 'version=' bamboo.log | egrep --color -o '[^[:space:],"](.+.)+.+;version=["]*([[:digit:]]+.)+[[:digit:]]["]*' > tmp
cut -d ';' -f 1 tmp| tr '.' '/'| sed 's/$//version/'

I would do something like that:

cut -d ';' -f 1 tmp| tr '.' '/'| sed 's/$//version/'| echo $(cut -d '=' -f 2 < tmp) ) > -

Of course it doesn't work.

But I don't know how I can paste pipe (what is coming from pipe) as the name of file and simple version to 'echo'.

Could you help me with this problem?
