copy file and rename n times in succession

coryjsanders · 12-07-2012, 10:56 PM

I have this:
#!/bin/bash
#copies named iax modem and saves in ensuing order

cp /etc/iaxmodem/iaxmodem-cfg.ttyIAX20 /etc/iaxmodem/iaxmodem-cfg.ttyIAX21

But would like to create the contents of iaxmodem-cfg.ttyIAX20 n more times and name 22, 23 24, etc

Use a loop:

Code:

for c in {22..28}
do
  cp /etc/iaxmodem/iaxmodem-cfg.ttyIAX20 /etc/iaxmodem/iaxmodem-cfg.ttyIAX$c
done

Or alternatively you can use:

Code:

#!/bin/bash
echo -n "Enter how many times: "; read times
n=20
while [ $n -le $times ]
do
cp  /etc/iaxmodem/iaxmodem-cfg.ttyIAX /etc/iaxmodem/iaxmodem-cfg.ttyIAX$n
n=$((n+1))
done
