How after a long wait for the output to save what I saw in the file?

Let's say by command:

git grep <regexp> $(git rev-list --all)

I understand that it would be prudent to have > log.txt at the end, I want to immediately save what I saw?

I figured it out myself, the essence is as follows. If we just allow typing just git log , a browse dialog will appear with the icon : This screen can be moved up and down there, but if you press the s button, then the dialog for entering the file name appears, you only need to type in log.txt and all the output will be saved to this file

To see the output and save it at the same time there is a special command tee , example:

 command | tee log.txt

  • I know this command, I use it from time to time, however I cannot remember it all the time and insert it where necessary and inappropriately. this operation takes a very long time if there are many commits - RinatV
  • Most terminals support logging. Customize yourself and will not forget. But I think it will help to simply increase the buffer for the terminal - then scrolling will be available. - KoVadim

If not for a single command, but for a "session", then I use the script command
(the entire work protocol will be in the ./typescript file, but in general, see man script ).
