Shell Programming and Scripting

Dear Experts,

I have a file containing text like below

123
456
789
012
345

I want to save each line in array.
and print each array index as per my requirement.

For Example array[2] will print 456
array[4] will print 012

Thanks for your Help.

Code:

awk '{ array[NR] = $0 } END { print array[2]; print array[4]; }' file

Dear era/friends,

Many thanks for your help!!
I have i more query.

I have a file with three columns and below mentioned script print all three columns perfectly.

awk '{bts[NR]=$1;tre[NR]=$2;bss[NR]=$3}
END{{printf "%s\t", bts[1]; printf "%s\t", tre[1];printf "%s\n", bss[1];} }'

But if i replace print command with my desired command it give me following error message:

./tre_alarm.sh: line 34: syntax error near unexpected token `('

Below is the script i used:
awk '{bts[NR]=$1;tre[NR]=$2;bss[NR]=$3}
END{for (i=1;i<=NR;i++){ omcdo -cmd 'TRE_reset(bts[i],bss[i],"tre[i]")'} }' Output_TRE_ALARM.txt

it is working fine when used on command prompt with out script:
Actual command:

omcdo -cmd 'TRE_reset(12,23,"27")'

Thanks for your help

Can anybody help me with this i will be very thankful to him.

actually when awk came across first ' it consider it as end so try \' for your command..

BOSS!!!
The new script is

awk '{bts[NR]=$1;tre[NR]=$2;bss[NR]=$3}
END{for (i=1;i<=NR;i++){ omcdo -cmd \'TRE_reset(bts[i],bss[i],"tre[i]")\'} }' Output_TRE_ALARM.txt

But still it is not working, what do you say about the inverted commas, should it be like this !!!

Thanks for the help!!

TRE_reset(bts[i],bss[i],"tre[i]")
what is this?? a function??
