Ubuntu 11.xx fix
Hvis systemet ikke kommer med en login prompt efter instllation/upgradering
- alt+højre pil
- slette splash fra /etc/default/grub
- update-grub
Show Cron Jobs
This is how to show cron jobs from all users
for user in $(cut -f1 -d: /etc/passwd); do crontab -u $user -l; done
Copy Pub key to server
cat .ssh/id_rsa.pub | ssh git.tekkom.dk "cat >> .ssh/authorized_keys"
Ændre tidszonen
dpkg-reconfigure tzdata
Apache log analyzer
zcat access.log.*.gz | cut -d' ' -f1 | sort | uniq -c | sort -h -r -b | head -n 50 | while read cnt ip; do echo -ne "$cnt\t"; echo -ne "$ip "; echo -e "(`dig -x $ip | grep PTR | grep -v -E '^;' | tr ' \t' ' '|cut -d' ' -f5`)"; echo -e "`whois $ip| grep address | head -n1 | sed -e 's/^address:*/\t/'`"; done
Convert Images on Linux
To Thumbs
Alt dette piping sletter EXIF data
for i in *.JPG; do djpeg $i | pnmscale -width 800 | cjpeg -opti -progr -qual 90 > TN_$i; echo $i processed; done
Brug convert istedet den bevarer EXIF
for i in *.JPG; do convert -resize 800 -quality 90 $i TN_$i; echo $i processed; done
Kør din konvertering parallelt:
ls -1 *.jpg | parallel -j 5 --eta convert -resize 800 -quality 90 '{}' 'TN_{.}.jpg'
#Eksempel fra MAC'en
Dafs-MacBook-Air:101CANON rael$ sudo port install parallel
Dafs-MacBook-Air:101CANON rael$ ls -1 *.JPG | parallel -j 5 --eta convert -resize 800 -quality 90 '{}' 'thumb/TN_{.}.jpg'

Hvis den skal tælle op kan man bruge denne for løkke.
t=1; w=`ls -l | wc -l`; for i in *.JPG; do let t++ ; echo "Converted $i($t/$w)"; done
From BMP to JPG
for i in *.bmp; do convert $i $(basename $i bmp)jpg ; echo "Converted $i"; done
Configure Ubuntu to send mail on logon
aptitude install sendemail -y # Ja det er sendemail og ikke sendmail
echo "echo besked" | sendemail -f mailaddr@mydomain.local -t bruger@domain.local -u subject -s smtp.maildomain.local
Tilføj en linie i bunden af /etc/profile. Denne fil bliver kørt hver gang en bruger logger ind.
echo -e "$USER er loggint ind, her er de øvrige brugere: \n `who`" | sendemail -f mailaddr@mydomain.local -t bruger@domain.local -u subject -s smtp.maildomain.local
Fix ubuntu perl Language problem
apt-get install language-pack-en-base
export LANGUAGE=en_US.UTF-8
export LANG=en_US.UTF-8
export LC_ALL=en_US.UTF-8
locale-gen en_US.UTF-8
dpkg-reconfigure locales
IPv4 apt-get
apt-get -o Acquire::ForceIPv4=true install screen htop nmon -y
Tillad Sudo uden password
her får pi brugeren lov til at sudo uden password nano /etc/sudoers
pi ALL=(ALL) NOPASSWD: ALL
