15. Review Shell syntax • $# - Number of positional parameters • $! - Background PID • $? - Return value • $$ - Process PID • $ - Provides the content of a variable ($NUMBER) • $1, $2, $3 … - The syntax represents the positional parameters on the command line. • exit 0 – The return values is a number from 0 to 255. A value of zero (0) indicates a normal exit. • exit 1 - Indicates a failure.

16. Review shell syntax • “ “ - Double quotes. Removes special meaning of all enclosed characters, except $, `, “, and \. • Example: print “The price is $Price.\n”; (interpolation) • ‘ ’ - Literal quotes. Removes the special meaning of all enclosed characters. A single quote cannot appear within single quotes because a single quote denotes the end of the string. • ` ` - Single Back Slash quotes. Used for command substitution. • Example: echo The date is `date` (interpolation) • LINES=`wc -l $ENTRY | cut -c 1-7` • LISTING=`ls -l | cut -f 9`
