Exec Briefing Template - From that point on, all stdin comes from that file, rather than its normal source (usually keyboard input). The exec will replace the current process with the process resulting from executing its argument. Exec replaces the current program in the current. The use of fork and exec exemplifies the spirit of unix in that it provides a very simple way to start new tasks. Exec returns the last line of the output by default, but can provide all output as an array specifed as the second parameter. I have seen exec command used inside scripts to redirect all output to a file (as seen in this). Please anyone explain these functions. An exec <filename command redirects stdin to a file. What is the exec() function and its family? You can use the util library that comes with nodejs to get a promise from the exec command and can use that output as you need.

Possible duplicate of what are the different versions of exec used for in c and c++?, what is the difference between the functions of the exec family of system calls like exec. From that point on, all stdin comes from that file, rather than its normal source (usually keyboard input). Shell_exec returns all of the output stream as a string. But in simple words, what does it do? What is the exec() function and its family? The old exec statement circumvented this, because the compiler knew that if an exec without globals/locals args occurred in a function, that namespace would be. Note the use of the word task here, i have deliberately avoided. The use of fork and exec exemplifies the spirit of unix in that it provides a very simple way to start new tasks. In short, exec $@ will run the command given by the command line parameters. Exec returns the last line of the output by default, but can provide all output as an array specifed as the second parameter.

Why is this function used and how does its work? But in simple words, what does it do? An exec <filename command redirects stdin to a file. The exec will replace the current process with the process resulting from executing its argument.
