Question

2 Aliases

2a: Create an alias, numberfiles, which prints the number of files in the current directory

??

2b: Using an alias, replace ls so that it now always shows hidden files.

??

2c: Create an alias, fox1, which uses ssh to attempt to log you into fox01.cs.utsa.edu and prompt you for your password.

??

2d: Assuming the variable $var is set to 100, create an alias, whatIsVar, which echos the current value of $var. Note that if $var changes to another value, whatIsVar should reflect that automatically.

??

2e: Solve the same problem above, except make it so that whatWasVar always prints the original value of $var (i.e., if $var changes, whatIsVar continues to print 100).

??

Answer 1

2a: alias numberfiles="ls -1 | wc -l"

2b: alias ls="ls -A"

2c: alias fox1="ssh fox01.cs.utsa.edu"

2d: alias whatIsVar="echo ${var}"

2e: alias whatWasVar="echo $var"
