hi

i want to know if there is a command by which i can see how much time it takes for a complete execution of script of program.

also is there any way for line by line debugging of shell script i.e. to execute one line at a time.

there is a command time to do that:
time <your command>
(see man page of bash)

is there a way to debug a single line at a time i know the -xv way

Just set/unset xv per line eg

Code:

set -xv; a=(a "b 2" c); set +xv

Incidentally, there's 2 ways to time a script

Code:

# just time
time ./t2.sh
a
b 2
c

real	0m0.003s
user	0m0.001s
sys	0m0.003s

# time & mem & cpu & ....
\time ./t2.sh
a
b 2
c

0.00user 0.00system 0:00.00elapsed 50%CPU (0avgtext+0avgdata 4800maxresident)k
0inputs+0outputs (0major+339minor)pagefaults 0swaps

I found this, but quite old: http://archive09.linux.com/feature/153383 or http://bashdb.sourceforge.net/bashdb.html
