dmesg è sacro

Quando mi loggo su una macchina Unix, io DEVO digitare "dmesg". E' più forte di me. Ognuno ha i suoi riti, lancia ksh -o vi, da invio $random volte alternato al comando cd ...

Io digito dmesg e do invio. Su Linux, su Solaris ...

Su Aix non c'è!

E non c'è alog -o -t boot o errpt -a che tenga.

Per questo sono arrivato a farmelo da me:

root@localhost / #which dmesg

/usr/bin/dmesg

root@localhost / #file /usr/bin/dmesg

/usr/bin/dmesg: shell script

root@localhost / #cat /usr/bin/dmesg

#!/usr/bin/bash

cat /var/adm/messages

root@localhost / #dmesg

Ebbene si :)

Allo stesso modo pgrep:

root@localhost / #which pgrep

/usr/bin/pgrep

root@localhost / #file /usr/bin/pgrep

/usr/bin/pgrep: shell script

root@localhost / #cat /usr/bin/pgrep

#!/usr/bin/bash

# My Pgrep Work in Progress 0.1

if [ $1 = "-h" ];then

echo "Usage:\n";

echo "Useful options are f and N";

echo "ps options A and e are implicited";

echo "Es:\n";

echo "pgrep Nf blabla"

else

ps -Ae${1}|grep $2|awk '{print $1,$2,$8}'
