Here with I am submitting a script [File attached too], which is made for my use. It may be useful for anyone. I did't given in functions and all..[little lazy]..
I am posting in this forum , because anyone can reply to this thread , for any change/addition.
1) We often get the "linux newbie memory freakout" here. A new user may see "56M free" and panic -- rebooting obsessively when free gets low, plugging bizzare and harmful values into /proc/vm to "flush the cache", and sometimes even reformatting just to try and solve an imaginary memory leak. Any decently busy system converts 'free' to 'cache' in short order, which is fine -- cache is as good as free.
2) It'd be better to leave dmidecode out than demand random people run your untested script as root.
3) Run ifconfig with the full path, /sbin/ifconfig, so non-root users can find it.
4) Not everyone has java. Test if java exists before trying to get its version.
5) You can get disk information without root and fdisk, as well as tons of other stuff, via /sys:
Code:
# Sizes and models of all hard drives
TOTAL=0
for X in /sys/class/block/[sh]d[a-z]
do
D=$(basename ${X})
read TYPE < ${X}/removable
read SIZE < ${X}/size
read MODEL <"${X}/device/model"
[ "$TYPE" = 0 ] || continue # Ignore removable drives
set -- ${X}[1-9]* # Set $# to the number of partitions
TOTAL=$((TOTAL + SIZE))
echo "$D[1-$#]: $(((SIZE*512)/(1000*1000*1000)))GB $MODEL"
done
echo "Total: $(( (TOTAL*512)/(1000*1000*1000) )) GB"
# MAC addresses of all network cards
for DEV in /sys/class/net/*
do
D=`basename $DEV`
[ "$D" = "lo" ] && continue # Ignore loopback
[ "$D" = "sit0" ] && continue # Ignore ipv6 tunnel
read MAC < $DEV/address
echo "$D mac $MAC"
done
# Get some DMI information without needing root
cat /sys/class/dmi/id/* 2>/dev/null
