linux - Use pipe line to open a file after it's just created -

i want accomplish quite simple pipeline:

step 1 : cat input1 input2 > output

step 2 : gedit output

i can

cat input1 input2 > output | gedit output

but wonder how can ommit typing name of output file in case? file created cat redirect should file gedit open. thanks!

just define bash function purpose (perhaps in ~/.bashrc if want create permanent), e.g.

editcat() { cat $* > output gedit output }

you might want create function more fancy, generating output file temporary file using mktemp(1)

editcat() { local editemp=$(mktemp) cat $* > $editemp gedit $editemp rm $editemp }

but might consider using less(1)

linux pipeline cat gedit
