hey guys, im doing a simple search program and i came up with a problem. What i am trying to achieve is, if the search is false(means the book does exist) , the program will then ask the user to input the information again(title and author) and do a search again until there is no such book and then display a message saying he can input a new book in.
i tried using a until loop, but it does not seem to work. some guidance on how the statement should be and where should it be placed?

sortbib
sortbib(1) User Commands sortbib(1)NAME
sortbib - sort a bibliographic database
SYNOPSIS
sortbib [-s KEYS] database...
DESCRIPTION
sortbib sorts files of records containing refer key-letters by user-specified keys. Records may be separated by blank lines, or by `.[' and
`.]' delimiters, but the two styles may not be mixed together. This program reads through each database and pulls out key fields, which are
sorted separately. The sorted key fields contain the file pointer, byte offset, and length of corresponding records. These records are
delivered using disk seeks and reads, so sortbib may not be used in a pipeline to read standard input.
The most common key-letters and their meanings are given below.
%A Author's name
%B Book containing article referenced
%C City (place of publication)
%D Date of publication
%E Editor of book containing article referenced
%F Footnote number or label (supplied by refer)
%G Government order number
%H Header commentary, printed before reference
%I Issuer (publisher)
%J Journal containing article
%K Keywords to use in locating reference
%L Label field used by -k option of refer
%M Bell Labs Memorandum (undefined)
%N Number within volume
%O Other commentary, printed at end of reference
%P Page number(s)
%Q Corporate or Foreign Author (unreversed)
%R Report, paper, or thesis (unpublished)
%S Series title
%T Title of article or book
%V Volume number
%X Abstract -- used by roffbib, not by refer
%Y,Z Ignored by refer
By default, sortbib alphabetizes by the first %A and the %D fields, which contain the senior author and date.
sortbib sorts on the last word on the %A line, which is assumed to be the author's last name. A word in the final position, such as `jr.'
or `ed.', will be ignored if the name beforehand ends with a comma. Authors with two-word last names or unusual constructions can be sorted
correctly by using the nroff convention ` ' in place of a blank. A %Q field is considered to be the same as %A, except sorting begins with
the first, not the last, word. sortbib sorts on the last word of the %D line, usually the year. It also ignores leading articles (like `A'
or `The') when sorting by titles in the %T or %J fields; it will ignore articles of any modern European language. If a sort-significant
field is absent from a record, sortbib places that record before other records containing that field.
No more than 16 databases may be sorted together at one time. Records longer than 4096 characters will be truncated.
OPTIONS -sKEYS Specify new KEYS. For instance, -sATD will sort by author, title, and date, while -sA+D will sort by all authors, and date. Sort
keys past the fourth are not meaningful.

Records with missing author fields should probably be sorted by title.
