script output not proper using kickstart installation

Hi All,

I am creating a custom iso in which i need to transfer one small script via kickstart.cfg file to /etc/profile in post installation section but it wont copied cleanly:

cat >> /usr/local/bin/script << EOF_script

#!/bin/bash

PROCCOUNT=`ps -l | wc -l`
PROCCOUNT=`expr $PROCCOUNT - 4`
if [[ $(groups) == *irc* ]]; then
ENDPROC=`cat /etc/security/limits.conf | grep "@irc" | grep nproc | awk {'print $4'}`
ENDSESSION=`cat /etc/security/limits.conf | grep "@irc" | grep maxlogins | awk {'print $4'}`
PRIVLAGED="IRC Account"
else
ENDPROC=`cat /etc/security/limits.conf | grep "*" | grep nproc | awk {'print $4'}`
ENDSESSION="Unlimited"
PRIVLAGED="Regular User"
fi

echo -e "

+++++++++++++++++: System Data :+++++++++++++++++++
+ Hostname = `hostname`
+ Address = `/sbin/ifconfig eth0 | grep 'inet addr:' | cut -d: -f2 | awk '{ print $1}'`
+ Kernel = `uname -r`
+ Server Installation Date = `rpm -qi basesystem | grep Install | cut -c 15-46`
+ Uptime = `uptime | sed 's/.*up ([^,]*), .*/1/'`
+ No of CPU = `grep processor /proc/cpuinfo | wc -l`
+ `lscpu | grep 'socket'`
+ Memory = `cat /proc/meminfo | grep MemTotal | awk {'print $2'}` kB
++++++++++++++++++: User Data :++++++++++++++++++++
+ Username = `whoami`
+ Privlages = $PRIVLAGED
+ Sessions = `who | grep $USER | wc -l` of $ENDSESSION MAX
+ Processes = $PROCCOUNT of $ENDPROC MAX
+++++++++++++++++++++++++++++++++++++++++++++++++++
"

EOF_script

above data should be copied as it is in /etc/profile to run properly but actually it get copied the output of above commands.

kindly help - i tried with echo"" also but same thing happening

gelonida

could you just try with a simpler example and then enhance step by step till it breaks?

Two other small questions.
Why do you >> /usr/local/bin/script
this should be
> /usr/local/bin/script

>> appends to an existing script, but if you append, then the line
#!/bin/bash is useless as it works only as the first line of a script.

I'd suggest to try

cat >> /usr/local/bin/script << EOF_script
#!/bin/bash
touch /tmp/afile
EOF_script

Open in new window

make also sure that you have no trailing white spaces in the lines containing 'EOF_script'

Will the file be created?

thanks for your feedback - actually most of the part copied sucessfully but issues is this it copied after the command executed . but i want it to go without execution .i dont want ouput i want same script as it is after kickstart installation

For example

Hostname = `hostname` line copied as Hostname = local.domain which i dont want.

i want it as Hostname = `hostname` only

gelonida

OK. please look at following script

#!/bin/bash

a=3

echo without quotes
cat << eot
$a b c `date`
eot

echo with single quotes
cat << 'eot'
$a b c `date`
eot

Open in new window

and its output:

without quotes
3 b c Tue, Apr 14, 2015  6:27:28 PM
with single quotes
$a b c `date`

Open in new window

if you don't want expansion in the << eot, then use quotes

Thank you looks good - i will test it tommorrow and let you know.

I have also post 2 more question for kickstart only - if you get chance please have a look and advice! thanks

gelonida

Well I hope my answer helps.
Unfortunaely I don't know kickstart, so probably can't help a lot there.

Hi Gelonida - it didnt work - even bad then before - kindly help

gelonida

Could you post your changed script?
Or perhaps even better:
the shortest possible script that shows the problem?

did you use cat or did you use echo?

Here it is:

cat >> `/usr/local/bin/dynmotd' << EOF_dynmotd


#!/bin/bash

PROCCOUNT=`ps -l | wc -l`
PROCCOUNT=`expr $PROCCOUNT - 4`
if [[ $(groups) == *irc* ]]; then
ENDPROC=`cat /etc/security/limits.conf | grep "@irc" | grep nproc | awk {'print $4'}`
ENDSESSION=`cat /etc/security/limits.conf | grep "@irc" | grep maxlogins | awk {'print $4'}`
PRIVLAGED="IRC Account"
else
ENDPROC=`cat /etc/security/limits.conf | grep "*" | grep nproc | awk {'print $4'}`
ENDSESSION="Unlimited"
PRIVLAGED="Regular User"
fi

echo -e "
