I am writing a for loop that will go through this file line by line creating a variable of itself. Using the first iteration of the loop (i.e. the first line) as an example, I want it to create a variable called
db_serial and populate it with value 0623AN1208
on the next iteration create a variable called
db_hostname and populate it with value server1
etc etc
so i have tried
Code:
cat /tmp/CMDB | while read n
do
VAR=db_`echo $n | cut -d: -f1`
VALUE=`echo $n | cut -d: -f2`
eval `echo $VAR`=`echo $VALUE`
done
# echo it all out after the loop has finished
echo "DB serial is set to $db_serial"
echo "DB hostname is set to $db_hostname"
echo "DB model is set to $db_model"
echo "DB Asset ID is set to $db_assetID"
Plus a whole load of other combinations and i just cant get the thing to work
Im sure the problem is with my use of the "eval" command which is effectively using another variable to create a variable, and assigning the value from another variable
I would like to know how to pass a variable inside a variable to a function.
sample code below
--------------
for x in 1 9
do
check_null $C$x ##call function to check if the value is null
if
then
echo "line number:$var_cnt,... (2 Replies)

echo
echo(1B) SunOS/BSD Compatibility Package Commands echo(1B)NAME
echo - echo arguments to standard output
SYNOPSIS
/usr/ucb/echo [-n] [argument]
DESCRIPTION
echo writes its arguments, separated by BLANKs and terminated by a NEWLINE, to the standard output.
echo is useful for producing diagnostics in command files and for sending known data into a pipe, and for displaying the contents of envi-
ronment variables.
For example, you can use echo to determine how many subdirectories below the root directory (/) is your current directory, as follows:
o echo your current-working-directory's full pathname
o pipe the output through tr to translate the path's embedded slash-characters into space-characters
o pipe that output through wc -w for a count of the names in your path.
example% /usr/bin/echo "echo $PWD | tr '/' ' ' | wc -w"
See tr(1) and wc(1) for their functionality.
The shells csh(1), ksh(1), and sh(1), each have an echo built-in command, which, by default, will have precedence, and will be invoked if
the user calls echo without a full pathname. /usr/ucb/echo and csh's echo() have an -n option, but do not understand back-slashed escape
characters. sh's echo(), ksh's echo(), and /usr/bin/echo, on the other hand, understand the black-slashed escape characters, and ksh's
echo() also understands a as the audible bell character; however, these commands do not have an -n option.
OPTIONS -n Do not add the NEWLINE to the output.
