n00b scripting

Train · 06-03-2014, 12:13 PM

Just playing around. I made this simple script to report things about the system.

And the 2nd script for printing the output to a physical printer.

[It works. This thread does not involve any direct questions.]

Code:

#!/bin/bash
# This script is for a system reporting.

echo "_____________"
echo -n "SYSTEM REPORT"
echo ""
echo "_____________"
echo -n "SYSTEM REPORT"
echo ""
echo "_____________"
echo -n "SYSTEM REPORT"
echo ""
echo "_____________"
echo ""
echo ""
echo "--------------------------------------------------"
echo -n "DATE and TIME:"
echo ""
echo "--------------------------------------------------"
date
echo ""
echo ""
echo "--------------------------------------------------"
echo -n "HOSTNAME:"
echo ""
echo "--------------------------------------------------"
hostname
echo ""
echo ""
echo "--------------------------------------------------"
echo -n "Up Time:"
echo ""
echo "--------------------------------------------------"
uptime
echo ""
echo ""
echo "--------------------------------------------------"
echo -n "LSB Version:"
echo ""
echo "--------------------------------------------------"
lsb_release -a
echo ""
echo ""
echo "--------------------------------------------------"
echo -n "Kernel Version:"
echo ""
echo "--------------------------------------------------"
uname -r
echo ""
echo ""
echo "--------------------------------------------------"
echo -n "Disk Usage:"
echo ""
echo "--------------------------------------------------"
df -h
echo ""
echo ""
echo -n "FSTAB:"
echo ""
cat /etc/fstab
echo ""
echo ""
echo -n "MTAB:"
echo ""
cat /etc/mtab
echo ""
echo ""
echo "--------------------------------------------------"
echo -n "CPU Information: "
echo ""
echo "--------------------------------------------------"
cat /proc/cpuinfo
echo ""
echo ""
echo "--------------------------------------------------"
echo -n "Memmory Information: "
echo ""
echo "--------------------------------------------------"
cat /proc/meminfo
echo ""
echo ""
echo "--------------------------------------------------"
echo -n "Networking Information: "
echo ""
echo "--------------------------------------------------"
ifconfig
route -n
#IP Ping
p=$(route -n | grep UG | tr -s " " | cut -f 2 -d " ")
pp="/bin/ping"
echo ""
echo "Checking to see if $p is up..."
echo ""
$pp -c 2 $p
echo ""
echo ""
echo "--------------------------------------------------"
echo -n "PCI Devices:"
echo ""
echo "--------------------------------------------------"
lspci
echo ""
echo ""
echo "____________________"
echo "END OF SYSTEM REPORT"
echo "____________________"
echo -n "END OF SYSTEM REPORT"
echo ""
echo "____________________"
echo -n "END OF SYSTEM REPORT"
echo ""
echo "____________________"

Code:

#!/bin/bash
echo "----------------------------------------------------"
echo -n "Printing System Report"
echo ""
echo "----------------------------------------------------"
echo -n "Which lp printer? (hplj) "
read device
: ${device:="hplj"}
./sr | lp -o scaling=100 -d $device

formatting from bash instead of

Code:

echo "_____________"

you could try making a variable or function to something like

Code:

NL=$(printf '%*s\n' "${COLUMNS:-$(tput cols)}" '' | tr ' ' _)
echo $NL

looks fun good tools too, thanks.

You could use

Code:

p=$(route -n | grep UG | awk '{print $2}')

pan64 · 06-04-2014, 01:34 AM

p=$(route -n | awk '/UG/{print $2}')
would be even simpler (and faster)

You could try using a heredoc to save on the high usage of echo, here is a small example:

Code:

cat <<EOF
_____________
SYSTEM REPORT

_____________
SYSTEM REPORT

_____________
SYSTEM REPORT

_____________


--------------------------------------------------
DATE and TIME:

--------------------------------------------------
$(date)


--------------------------------------------------
HOSTNAME:

--------------------------------------------------
$(hostname)
EOF
