you can check for both the commands using man page

man awk
man basename

you can use in below manner . this code will give you only test in the output
Code:
basename test.txt .txt

you can use awk for almost ever thing using different combinations
can use for substr , printing any argument for n number of things

will show you few examples below

Code:
ll -rt | awk '{print$3}'

will print the third argument in the ll-rt o/p . By default delimeter used is space
Code:
ll -rt  | awk '{print $NF}'

will print the last argument of ll -rt o/p which will be the file or directory name
Code:
echo "test" | awk '{print substr ($0,2,3)}'

will print "est" in the o/p similar to our pl/sql fn substr
Code:
echo "test/test1" | awk -F "/" '{print$1}'

will print "test" in the o/p . Filtering is done on basis of "/" and print
1st argument i.e on left "/"

Similarly you can do many many more things with "awk" command
