Application of FG in Linux in Vim/vi

How to use FG to quickly return to vim?

When you use VIM to modify a parameter in a file, you cannot remember the parameters for a long time. It often appears that when we just opened this file with Vim, we forgot the parameters just now. At this point we need to temporarily exit this file to find parameters in a directory. Or, you have multiple open actions to close the same file.

So how do you make this kind of operation easier and quicker?

Now if you forget the parameters in the directory/var/lib/rpm/group, the file to operate is called A.txt. In general, the procedure is: Wq or: ZZ, and then cat/var/lib/rpm/group view the parameters and copy. Then use the command vim a.txt into the a.txt and paste to the corresponding position.

One solution is to use FG.

After we use VIM a.txt found to forget parameters, then back to the command mode, press the shortcut combination of CTRL + Z, which is to put the A.txt file in the open state in the background. Once the parameters are found and the FG is entered on the command line, return to the A.txt file immediately. Multiple operations each exit file can be used Ctrl + Z, until finished, then use: Wq save exit.

There are, of course, BG orders, which are not detailed here.

Advantages: Multiple Entry Exit file operation efficiency significantly increased.
