Hello,
I'm attempting to modify a script so it can be executed via a batch scheduler. Part of the script calls a program called direct (which I believe may have something to do with Connect Direct). I have tried cat and vi on the file; cat returns absolute gibberish, vi states the file is... (2 Replies)
hi, I want to determine the position of specific values over a cutoff.
So I have a string of values that are mainly negative in number and I want to print the rare few that are positive. Specifically I want to know the position of the value along the string. The position is based from right to... (11 Replies)
Stupid question, but is there an ANSI C stdlib function that will do this for me? I want to pass the function a path and determine if the current process can read/write/execute on the path. I suppose I can whip something up using fstat and then determining the current process's user/group IDs and... (6 Replies)

Hi all,
When I use an editor (vi) that is spawned in a remote server, visually I could see the latency between typing a character/word and being displayed on the terminal. I could see this visually but how do I get a metric on this or how to quantify this?
As expected, when I type in a editor... (6 Replies)
Hello,
I have a flat file with a list of files with the path to the file and I am attempting to calculate the filesize for each one; however xargs isn't playing nicely and I am sure there is probably a better way of doing this.
What I envisioned is this:
cat filename|xargs -i ls -l {} |awk... (4 Replies)
Hi,
I was hoping someone could suggest an alternative to code I currently have as mine takes up far too much processor time and it to slow.
The situation:

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.
