Hello

I have a few questions about writing scripts.

1. Who do I change a file into a string. My file contain fields like " inr05, inr02, ipr05 ". What is the syntax ?

2. my file contain fields like " inr05, inr02, ipr05 ". Who can I sort the file according to the last 2 characters ?

3. What is the syntax for the command " foreach " for a file. I know the syntax for a string

foreach lay ($string)
commands..
end

Thank a lot

hi there,

To put the contents of a file into a string use the cat command and a variable, something like this:


#!/bin/sh
FILE1=`cat myfile.txt`
echo $FILE1

This will display the contents of the file to the screen, then you can use other commands like sed, grep and awk depending on what you want to do with the variable. If you are wanting to find fields like `inr05`, use grep and awk:

#!/bin/sh
FILE1=`cat myfile.txt | grep "inr05" | awk '{print $1}'`


You really need to read up on bash scripting and also how to use grep. sed and awk very useful commands if your going to do any scripting

Hi

the file i have contain the following fildes"

record #1: ipr05
record #2: inr02
record #3: ipr04
record #1: ipr03

I need to sort this file by the 2 last digits, ( 05, 02, 04, 03)after sorting the file the order of the record should like this:

record #1: inr02
record #2: ipr03
record #3: ipr04
record #1: ipr05

What is the command and the syntax for it ?

Thank's a lot
