hi i am trying to save the values i extract from a file with the help of awk in a bash shell array.
i have:
it prints just blank lines.
What is in file2?

file1 has two columns and i am trying to save the first column into an array..

this is not working.. any ideas what is wrong here?
There are so many things wrong with that piece of code that it's hard to know where to begin.
That code is reading the entire file into an array for every line of the file. I tried it with a 9-line file, and it created 81 lines of output. If you got blank lines, you are probably reading the wrong file.
If you want to put the first field of a file into an array, there are many ways to do it. For example, using a while loop as you have:
More efficient is:

Hi,
Is is possible to get the value using shell script?
x=1
y1 = 10
y2 = 15
y3 = 7
echo $y$x is giving y1 (variable name)
but I need the value of y1 (i.e. 10 dynamically)
Is there any solution?
if so, please mail me at kkodava@maxis.com.my

I'm at wits end with this issue and my troubleshooting leads me to believe it is a problem with the file formatting of the array referenced by my script:

else {print a "," $0}}' WBTSassignments1.txt RNCalarms.tmp
On the WBTSassignments1.txt file... (2 Replies)
