Inserting spaces after a value in UNIX
Hi All,

I need to prepare a shell script in UNIX to insert 400 spaces after a variable in a file "file.txt".

Eg. if n=T12345
echo $n >> file.txt

cat file.txt should give:
T12345<400 spaces>

Please advice.

Thanks in advance !!

Hi.

As I said here: https://www.unix.com/shell-programmin...-variable.html

Thanks for the reply Scottn !!

I tried the same:
printf "$n%400s" >> file.txt

Although it is inserting the required number of spaces in file.txt, it also gives the message:
printf: 400s: No such file or directory
printf: No such file or directory

Can you please advice.

You must be doing something else (or using a funny shell! - which shell are you using?)

Show the code you are running, as that piece of code is fine:

Code:
$ echo $n
123
$ printf "$n%400s" >> file.txt
$ wc -c file.txt
403 file.txt

Hi Scottn,

I am using ksh:

$ echo $SHELL
/bin/ksh

That's not a funny shell!

I was hoping you'd post some code so that I could see exactly what you were doing that would give this error...
