Hi all,
Am working on a script to understand the flow control of it..
Since i am from a C background i looking out for an easy way to analyze the script as it runs ..
In C/C++ we have F7 that starts execution from main() and proceeds accordingly..
I was wondering if there is a same approach... (2 Replies)

hi all
only the weirdest thing happened with me just now. I was debugging a shell script and I found that a step that was supposed to execute later was getting executed prior to another step for no reason. You know any ?

In the above array, I am trying to get the computer to tell me at what indices the non-zeros are at.
I don't understand why this doesn't work...
grep -v -b "0" ph.txt > position.txt
Isn't grep -v supposed to show non matches in Bash?... (2 Replies)

echo
echo(1B) SunOS/BSD Compatibility Package Commands echo(1B)NAME
echo - echo arguments to standard output
SYNOPSIS
/usr/ucb/echo [-n] [argument]
DESCRIPTION
echo writes its arguments, separated by BLANKs and terminated by a NEWLINE, to the standard output.
echo is useful for producing diagnostics in command files and for sending known data into a pipe, and for displaying the contents of envi-
ronment variables.
For example, you can use echo to determine how many subdirectories below the root directory (/) is your current directory, as follows:
o echo your current-working-directory's full pathname
o pipe the output through tr to translate the path's embedded slash-characters into space-characters
o pipe that output through wc -w for a count of the names in your path.
example% /usr/bin/echo "echo $PWD | tr '/' ' ' | wc -w"
See tr(1) and wc(1) for their functionality.
The shells csh(1), ksh(1), and sh(1), each have an echo built-in command, which, by default, will have precedence, and will be invoked if
the user calls echo without a full pathname. /usr/ucb/echo and csh's echo() have an -n option, but do not understand back-slashed escape
characters. sh's echo(), ksh's echo(), and /usr/bin/echo, on the other hand, understand the black-slashed escape characters, and ksh's
echo() also understands a as the audible bell character; however, these commands do not have an -n option.
OPTIONS -n Do not add the NEWLINE to the output.
