Using regex in sed to validate the length of an entry
I'm having trouble using sed to validate the length of an entry. I want to have a user enter a phone number of either length 7, 10 or 11. Only numbers are allowed. Does anyone know how to do this? Here's the code I have so far. It only validates that numbers are entered but not the length.
My defaul shell is /bin/ksh
I want to make multi entry sed changes to files
mainly because is easier for me to check my arguments in that
format, than all in just one line. example
sed '
> s/this/for this/
> s/that/for that/
> s/I/me/' filex > filez

sed "s/XYZ:1/XYZ:3/g" abc.txt > xyz.txt
when abc.txt contains lines of small length(currently around 80 chars) , this sed command is working fine.

Hi guys, I'm new to bash programming, so please pardon me.
I'm trying to replace an entry's text in Books.txt
This code works perfectly:
sed -i "s/$BookTitle/$NewBookTitle/g" Books.txt

phones(4) File Formats phones(4)NAME
phones - remote host phone number database
SYNOPSIS
/etc/phones
DESCRIPTION
The file /etc/phones contains the system-wide private phone numbers for the tip(1) program. /etc/phones is normally unreadable, and so may
contain privileged information. The format of /etc/phones is a series of lines of the form:
<system-name>[ ]*<phone-number>.
The system name is one of those defined in the remote(4) file and the phone number is constructed from [0123456789-=*%]. The `=' and `*'
characters are indicators to the auto call units to pause and wait for a second dial tone (when going through an exchange). The `=' is
required by the DF02-AC and the `*' is required by the BIZCOMP 1030.
Comment lines are lines containing a `#' sign in the first column of the line.
Only one phone number per line is permitted. However, if more than one line in the file contains the same system name tip(1) will attempt
to dial each one in turn, until it establishes a connection.
