Answer
You do not mention the programming language you intend to use. The implementation of looping constructs differs from one programming language to another. For instance, in the 'C' programming language, you might do something like the following:
for(;;) {
/* Some code or other would go here to do something. */
}
The above indicates an 'Endless Loop' in 'C'.
If programming in Ruby, Basic, Fortran, Perl, Python, PHP, Shell, Awk (including Nawk and Gawk) or one of the many other programming languages available on Unix/Linux systems, your 'for' loop may look very different. [JMH]
There is no traditional 'execute' command in Unix.
In Unix, use the 'man' command.
Use the command 'passwd'
cat /proc/version The above answer will only work on certain systems. For most Unix systems, use the 'uname' command to get the Unix version. AIX uses the oslevel command.
I don't know about a SEQ command, but the 'seq' command in Unix will print a sequence of numbers from first to last, with a given increment. Use the 'man seq' command to find out how to use it.
Use useradd command
Use the 'mkdir' command
For Unix/Linux, use the command 'cd /' For Windows, you can also use the same command or 'cd \'
Advanced Programming in the Unix Environment was created in 1992.
The -exec option executes the following command on a target of the 'find' command.
Use the 'grep' command
There is no standard 'format' command in Unix.
