Re,

  Je suis heureux de vous présenter la V0.0.6 de certShow.sh

  Usage: ${0##*/} [OPTIONS] <IP ADDRESS|HOST|FILE> [IP ADDRESS|HOST|FILE] ...
        -p Integer Max number of concurrent parallel process to run ($maxProc)
        -f String   Time format string ('$timeFmt')
        -d Integer  Number of days left before warning ($warnDays)
+       -n Float    Nice: delay in seconds between requests (implie "-p 1")
        -a          Show alternatives names
        -e          Show error stats
        -s          Show all stats
        -q          Quiet (Don't show line with status ok)
+       -u          Use Unicode symbols
        -h          Show this help

Ajouté l'option "-n <float delay in seconds>" (implie "-p 1").

Tu as raison: "avoid useless cat". J'avais initialement écrit:
   /pathTo/certShow.sh -q $(</pathTo/siteList.txt) 
mais c'est un bashism

In fine, j'ai ajouté la possibilité de lire la liste par stdin 

      /pathTo/certShow.sh -q www.domain1.com </pathTo/siteList.txt

J'ai ajouté l'option "-u Use Unicode symbols".

Du coup, une ligne crontab pourrait ressembler à:

  '10 7 * * * /pathTo/certShow.sh -qn 30 </pathTo/siteList.txt'

Merci Marc pour tes commentaires!
