システム管理者がコマンドラインからプログラムを起動した後、Ctrl+Zを押してシェルプロンプトが表示されました。プログラムに戻るには、管理者は次のうちどのコマンドを使用できますか?
正解:A
Ctrl+Z suspended the process, and "fg" will bring it back into the foreground of the shell A Comprehensive and Detailed To go back to a program that was suspended by pressing Ctrl+Z in the command line, the command that can be used is fg. The fg command stands for foreground, and it resumes the job that is next in the queue and brings it to the foreground.
Alternatively, if there are more than one suspended jobs, fg can be followed by a job number to resume a specific job.
