Post subject: | Making ver.sh more usefull |
Hi, I don't know if this is really the right place to put this but I find this little tweak I do quite handy. As far as I can see the current "version" is about useless for the general world. It gives information that would only be used to for working on a problem. I work on a lot of problems, but my short term memory sort of sucks a little so I use "version" to help me along the way. I do several things to Cecil's original ver.sh so that It will help me when I need a memory prompt. First, I add two lines to /usr/local/bin/mythbackup #!/bin/bash echo -n "Last Backup was on ">/home/mythtv/lbu.txt date >>/home/mythtv/lbu.txt Then I add a line to /etc/X11/fluxbox/keys echo "Mod1 v :ExecCommand ver.sh" >>/etc/X11/fluxbox/keys Put in an entry into mythtv crontab # Daily Drive space checkup 0 20 * * * sh /usr/bin/run-space-check.sh &>/dev/null And add a modified (original was posted on forum somewhere) script called /usr/bin/run-space-check.sh Code: #!/bin/sh # Drive space warning script #------------------------------------------------------------- lsmod |grep "ivtvfb "|cut -b1-6 >/tmp/tv if [ "$(cat /tmp/tv)" = "ivtvfb" ]; then fontsize="25" fontcolor="lightyellow" else fontsize="34" fontcolor="yellow" fi export DISPLAY=:0 export FONT="-adobe-helvetica-bold-*-*-*-$fontsize-*-*-*-*-*-*-*" #---------------------------------------------------------------- email=0 # 1 or greater to enable email show=1 # 1 to show osd echo -n "" > /tmp/tts # Nice to know when things happen ALERT_PERCENTAGE=75 # 90% disk used, ~500mb remaining on stock install? HOSTNAME=`hostname` RREMAINING=`df / |awk '{print $5}' |tail -1 |sed s/%//` # root status MREMAINING=`df /myth |awk '{print $5}' |tail -1 |sed s/%//` # myth status # root echo " Root Partition has used ${RREMAINING}% of space." >>/tmp/tts if [ $ALERT_PERCENTAGE -lt $RREMAINING ]; then date > /tmp/tts echo "WARNING, $HOSTNAME has ${RREMAINING}% root disk space used." >>/tmp/tts # bump flag email="$(($email + 1 ))" show="$(($show + 1 ))" fi ALERT_PERCENTAGE=85 # 85% myth partition used REMAINING=`df /myth |awk '{print $5}' |tail -1 |sed s/%//` # myth echo " Myth Partition has used ${MREMAINING}% of space." >>/tmp/tts if [ $ALERT_PERCENTAGE -lt $MREMAINING ]; then date > /tmp/tts echo "WARNING, $HOSTNAME has ${MREMAINING}% disk space used for media." >>/tmp/tts # bump flag #email="$(($email + 1 ))" #show="$(($show + 1 ))" fi # show it from here if flagged if [ $show -gt "1" ]; then cat /tmp/tts | osd_cat --l=8 --delay=6 --font=$FONT --shadow=3 --color=$ fontcolor --pos=bottom --align=centre & fi # email it from here if flagged if [ $email -gt "1" ]; then # Email me when root disk usage exceeds a specified percentage. date > /tmp/tts SENDER=mythtv@my.house RECIPIENT=emailme@my.work SMTP_SERVER=mail.my.isp df -h | sendEmail -f $SENDER -t $RECIPIENT -s $SMTP_SERVER -u "$HOSTNAME has ${RREMAINING}% root disk space used." email=0 fi #done Finally, I beat up on Cecil's original /usr/local/bin/ver.sh script to make it useful to me. Code: #!/bin/bash
killall osd_cat lsmod |grep "ivtvfb "|cut -b1-6 >/tmp/tv if [ "$(cat /tmp/tv)" = "ivtvfb" ]; then fontsize="25" fontcolor="lightyellow" else fontsize="34" fontcolor="yellow" fi export FONT="-adobe-helvetica-bold-*-*-*-$fontsize-*-*-*-*-*-*-*" export DISPLAY=:0 cat /etc/KnoppMyth-version > /tmp/ver date >> /tmp/ver echo "....." >> /tmp/ver /sbin/ifconfig |grep eth |cut -b1-4 >/tmp/net /sbin/ifconfig "$(cat /tmp/net)" | sed -n -e '/inet addr:\([0-9]*\.[0-9]*\.[0-9]*\.[0-9]*\).*/s//\1/p' | cut -c11-26 >/tmp/ip echo -n "IP $(cat /tmp/ip) _._ MythTV - " >> /tmp/ver cat /etc/hostname >> /tmp/ver echo "....." >> /tmp/ver cat /etc/mythtv/version >> /tmp/ver echo "....." >> /tmp/ver /usr/bin/run-space-check.sh cat /tmp/tts >> /tmp/ver cat /home/mythtv/lbu.txt >> /tmp/ver cat /tmp/ver | osd_cat --l=14 --delay=18 --font=$FONT --shadow=2 --color=$fontcolor --pos=middle --align=centre& Now when I press alt v or select version on the menu, I get some meat & potatoes. Those with a 350 card will see if the ivtvfb is loaded as the font changes color and size to work with a tv out display. One cavet, ip will be blank if you have two nics, you will have to manually select one or the other. ( l left room for improvments Smile ) Caution if doing copy and paste, watch for line wrapped lines! Many thanks to tjc & Human who made it possible for me to offer this.small token Smile Mike |

quick though. what format do you want the ip's listed as? if you replace the following: Code: /sbin/ifconfig |grep eth |cut -b1-4 >/tmp/net /sbin/ifconfig "$(cat /tmp/net)" | sed -n -e '/inet addr:\([0-9]*\.[0-9]*\.[0-9]*\.[0-9]*\).*/s//\1/p' | cut -c11-26 >/tmp/ip echo -n "IP $(cat /tmp/ip) _._ MythTV - " >> /tmp/ver with: Code: echo -n "IP(s) for Mythtv - " >> /tmp/ver echo "" >> /tmp/ver echo -n "$(/sbin/ifconfig |sed -n -e '/inet addr:\([0-9]*\.[0-9]*\.[0-9]*\.[0-9]*\).*/s//\1/p' |cut -c11-26)" >> /tmp/ver echo "" >> /tmp/ver you should wind up with something like this: Code: IP(s) for Mythtv -
172.16.2.63 1.2.3.4 127.0.0.1 Also, you dont have to create temp files for ip and net. by the way, the this also handles multiple network cards. IF I run the original script on my box, instead of only getting the ip for eth0, I get nothing due to the script bombing out trying to ifconfig "eth0 eth1" or something similar. |

PS: good work though, and I love the idea of having more information available onscreen. |

Hi, Thanks for the tips Not quite what I am after yet but does give me something to play with later on. Don't have the need for the lo ip to be displayed. For those boy scouts, the _._ MythTV should have a meaning. I did notice that I left out some other tid-bits that make for the rest of the information. In the /usr/local/bin/mythbackup script, I add : #!/bin/bash echo -n "Last Backup run "> /home/mythtv/lbu.txt date >> /home/mythtv/lbu.txt #---------------------------------------------------------------------------- That is for the those like myself that don't remember when the last backup was started And to compensate for the extra information, increase the line count to be ~ 18 in stead of 14 cat /tmp/ver | osd_cat --l=18 --delay=18 --font=$FONT --shadow=2 --color=$fontcolor --pos=middle --align=centre& If and when I find the original space script I will also post the link so there is proper credits It may not be pretty, but does work well enough for my needs. Thanks Mike |
