read n number of inputs

Hello,

I think its a sinple query but somehow i m stucked up here...

I am trying to enter n number of inputs from the user and write them in
an input file ie row wise...

I tried standard commands like


$echo "enter the inputs for the file"
$read var1 var2 var3 var4
test1 test2 test3 test4
$echo "$var1\n$var2\n$var3\n$var4" > input_file
$more input_file
test1
test2
test3
test4

However, the problem lies that i dont know how many inputs the user wants to enter
like
here we have 4 inputs but it may be 5,6 .... and so on...
so if we write till var4 it will not take var5 and var6....

Pls suggest where i am wrong or the possible solution...

Thakns In advance
Aparna

NAME
bup-restore - extract files from a backup set SYNOPSIS
bup restore [--outdir=outdir] [-v] [-q] DESCRIPTION
bup restore extracts files from a backup set (created with bup-save(1)) to the local filesystem. The specified paths are of the form /branch/revision/path/to/file. The components of the path are as follows: branch the name of the backup set to restore from; this corresponds to the --name (-n) option to bup save. revision the revision of the backup set to restore. The revision latest is always the most recent backup on the given branch. You can dis- cover other revisions using bup ls /branch. /path/to/file the original absolute filesystem path to the file you want to restore. For example, /etc/passwd. Note: if the /path/to/file is a directory, bup restore will restore that directory as well as recursively restoring all its contents. If /path/to/file is a directory ending in a slash (ie. /path/to/dir/), bup restore will restore the children of that directory directly to the current directory (or the --outdir). If the directory does not end in a slash, the children will be restored to a subdirectory of the current directory. See the EXAMPLES section to see how this works. OPTIONS
-C, --outdir=outdir create and change to directory outdir before extracting the files. -v, --verbose increase log output. Given once, prints every directory as it is restored; given twice, prints every file and directory. -q, --quiet don't show the progress meter. Normally, is stderr is a tty, a progress display is printed that shows the total number of files restored. EXAMPLE
Create a simple test backup set: $ bup index -u /etc $ bup save -n mybackup /etc/passwd /etc/profile Restore just one file: $ bup restore /mybackup/latest/etc/passwd Restoring: 1, done. $ ls -l passwd -rw-r--r-- 1 apenwarr apenwarr 1478 2010-09-08 03:06 passwd Restore the whole directory (no trailing slash): $ bup restore -C test1 /mybackup/latest/etc Restoring: 3, done. $ find test1 test1 test1/etc test1/etc/passwd test1/etc/profile Restore the whole directory (trailing slash): $ bup restore -C test2 /mybackup/latest/etc/ Restoring: 2, done. $ find test2 test2 test2/passwd test2/profile SEE ALSO
