Hi
Please help me to resolve.
Question:
I can run this command to change the mode of a device with id=500 as below
dbc "select device mode=3 where id=500;"
How can i run the same query with a file contaning n number of ids ?
file1.txt
12
234
34
500
34
45
Thanks in advance.
Use a loop, something like:
#/bin/sh
while read num
do
sqlstring="select device mode=3 where id="$num";"
dbc "$sqlstring"
done < file1.txt
You can do this by the following script.
while read line
do
dbc "select device mode=3 where id=$line;"
done < file1.txt
Thank you very much Frank and Raj, it works!!!
One small thing I added the dbc path for script to recog the dbc command.
