Hello,
I have a small script and it runs from web application in below format:
Code:
pipe:///path_to_myscript.sh url1 url2 url3
myscript.sh:
Code:
#!/bin/bash
count=0
while [ "$count" -lt "20" ]
do
count=$((count+1))
exec 3>&1
((ffmpeg -i $1 ...... -f mpegts pipe:1 2>/dev/null 1>&3 ) 2>&1 | \
while read LINE; do echo "$1 $LINE"; done 1>&2 ) 3>&1
PID=$!
wait ($PID)
if [ -n "$2" ]; then
((ffmpeg -i $2 ...... -f mpegts pipe:1 2>/dev/null 1>&3 ) 2>&1 | \
while read LINE; do echo "$2 $LINE"; done 1>&2 ) 3>&1
PID=$!
wait ($PID)
fi
if [ -n "$3" ]; then
((ffmpeg -i $3 ..... -f mpegts pipe:1 2>/dev/null 1>&3 ) 2>&1 | \
while read LINE; do echo "$3 $LINE"; done 1>&2 ) 3>&1
PID=$!
wait ($PID)
fi
sleep 1
done
When I run it, url1, or 2 or 3 runs but I am unable to see which one is in use and I do not wish to run iftop to detect. Htop is not giving any clue.
How may I change this script to be able to see the active url?
Thanks in advance
Boris

LEARN ABOUT SUNOS
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.
