Re: [monitoring-like] would like to be warned when I have mail (fetchmail -c)
Hello Michael It should work if you use just echo, as this is a shell builtin. If that 'echo something' is an external command or a pipe you have to use 'echo something || exit 1'. How exactly does the script look like? Here is the script: #!/bin/sh # Holt sich von fetchmail die Anzahl Mails und gibt diese aus. # # Author: Gerhard Siegesmund [EMAIL PROTECTED] FETCHMAIL='/usr/bin/fetchmail' while true; do $FETCHMAIL -c | sed -e 's/.* \([0-9]*\) messages (\([0-9]*\) seen.*/\1 - \2/g' | bc sleep 60 done Any suggestions? -- cu --== Jerri ==-- Homepage: http://www.jerri.de/ ICQ: 54160208 Public PGP Key: http://www.jerri.de/jerris_public_key.asc signature.asc Description: Digital signature ___ screen-users mailing list screen-users@gnu.org http://lists.gnu.org/mailman/listinfo/screen-users

Hello Will backtick 1 0 0 my_script.sh Why not get rid of the loop in your script and make screen run it every X seconds? That will solve your problem (although it doesn't really suggest the cause). I had that before. Problem is, that the call to the imap-server often takes several seconds. During this time screen freezes while writing the hardstatusline. -- cu --== Jerri ==-- Homepage: http://www.jerri.de/ ICQ: 54160208 Public PGP Key: http://www.jerri.de/jerris_public_key.asc signature.asc Description: Digital signature ___ screen-users mailing list screen-users@gnu.org http://lists.gnu.org/mailman/listinfo/screen-users

Mhm. There is not much to check. The script basically looks like this:
#!/bin/sh
while true; do
call_command_to_get something (e.g. fetchmail -c)
echo something
sleep some time

Re: [monitoring-like] would like to be warned when I have mail (fetchmail -c)
Hello I did something similar, but asking an imap-Server for the number of mails with fetchmail -c. Problem was: The query took several seconds to succeed, in which time my screen freezed as the hardstatusline was waiting for the info. I read the manpage and found backtick 1 0 0 script which is supposed to start the script and just wait for new messages to stdout to output them on the hardstatusline. Works great! Except for one thing: The script doesn't get killed, if the screen is ended. This means I have to stop the mailcheck-scripts which are created from screen by hand. Is there anything I can do to automatically stop the started scripts if the parent-screen is terminated? This seems to be a good opportunity to make use of the hardstatus and backticks. I agree a script is the right idea; here's how I'd do it. $ cat ~/bin/screen-checkmail #!/bin/sh fetchmail -c $OTHER_FETCHMAIL_JIGGERY_POKERY [parse fetchmail output reasonably] $ cat ~/.screenrc ... backtick 1 60 1 /$HOME/bin/screen-checkmail ... hardstatus alwayslastline ...%1`... Adding a conditional wrapper around your mail checker (eg %?...%?) will ensure that you only see your mail alert when your checkmail script produces output. -- cu --== Jerri ==-- Homepage: http://www.jerri.de/ ICQ: 54160208 Public PGP Key: http://www.jerri.de/jerris_public_key.asc signature.asc Description: Digital signature ___ screen-users mailing list screen-users@gnu.org http://lists.gnu.org/mailman/listinfo/screen-users
