Les tâches Cron régulières de la ferme
1er décembre 2010, parLa gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
Le super Cron (gestion_mutu_super_cron)
Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...) -

Run a function from while read line
2 octobre 2013, par user2783132I'm trying to run a function from while read line, the function contains ffmpeg commands to marge two files. but for some reason it's running the first
$line
and than breaks from loop."$filesList" contains three lines. I'm not sure what's wrong, but i can confirm with echo "$OFILE" that opener function runs three times if I
comment out
the ffmpeg commands, and only oncewith
ffmpeg commands.opener(){
OFILE="$1"
echo "$OFILE"
ffmpeg -i $opener_path -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate1.ts
ffmpeg -i $OFILE -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate2.ts
ffmpeg -i "concat:intermediate1.ts|intermediate2.ts" -c copy -bsf:a aac_adtstoasc merge_$OFILE
mv merge_$OFILE $OFILE
rm intermediate1.ts intermediate2.ts
}
while read line; do
if [ -e "$line" ]; then
opener "$line"
fi

Tailing a logfile and processing each line is missing data when converting a file with ffmpeg
8 avril 2014, par Chris.DI am running a script to tail a log file as per the code snippet below. I am running into a problem where by the line passed into $line is missing a number amount of bytes from the beginning when several lines are written to the log file at nearly the same time.
I can check the file afterwards and see that the offending line is complete in the file so why is it incomplete in the script. Some kind of buffering issue perhaps ?
The processing can sometimes take several seconds to complete would that make a difference ?
#!/bin/bash
tail -F /var/log/mylog.log | while read line
do
log "$line"
ffmpeg -i "from.wav" "to.mp3"
doneFull line in file
"12","","765467657","56753763","test"
example logged $line
657","56753763","test"
Update
I have done some more debugging of my code and it seems the processing that is causing the problem is a call to ffmpeg used to convert a wav to mp3. If I swap that with just a sleep then the problem goes away. Could ffmpeg effect the buffer somehow ? -
