I want to achieve something quite simple with pipeline:
step 1 : cat input1 input2 > output
step 2 : gedit output
I can do
cat input1 input2 > output | gedit output
But I wonder how can I ommit typing the name of output file in this case? So the file created from cat redirect should be the file gedit open. Thanks!
Just define a bash function for your purpose (perhaps in your ~/.bashrc if you want to make it permanent), e.g.
editcat() {
cat $* > output
gedit output
}
You might want to make that function more fancy, by generating the output file as a temporary file using mktemp(1)
editcat() {
local editemp=$(mktemp)
cat $* > $editemp
gedit $editemp
rm $editemp
}
But you might consider just using less(1)
You can try
gedit <(cat file1 file2)
or
cat input1 input2 | gedit
