CONDITIONAL SEQUENCES
SYNTAX: ON SUCCESS
commandi & & command2
ON FAILURE
commandi ||command2
EXERCISE: 1.Display the output, if the compilation of a program succeeds
2.0isplay an error message, if the compilation of a program fails
NOTE: AII built-in shell commands returns1(0) if they fail(succeed)
7.
GROUPING COMMANDS
SYNTAX: (command1; command2; command3.)
EXERCISE: 1.Repeat exercise 5.2, but, redirect the output to the same file.
NOTE: Grouping the commands causes them to be executed by a child shell and
the group may be redirected or piped as if it were a simple command
8.
BACKGROUND PROCESSING
SYNTAX: command &
EXERCISE: 1.Run a command/ exe file in background by redirecting its input
and output
NOTE: Background processing is very useful in performing several tasks
simultaneously as long as background tasks do not require standard
input
and output
9.
SHELL PROGRAMS: SCRIPTS
SYNTAX: scriptname
EXERCISE: 1.Write a script to include n different commands
NOTE: A file that contains shell commands is called a script. Before a script
can
be run, it must be given execute permission by using chmod utility
(chmod +x script). To run the script, only type its name. They are useful
for strong commonly used sequences of commands to full-blown
programs.
