For example, if I want to find if these files contain a string like "93849", what command I should use?

ROFFBIB(1) General Commands Manual ROFFBIB(1)NAME
roffbib - run off bibliographic database
SYNOPSIS
roffbib [ -e ] [ -h ] [ -n ] [ -o ] [ -r ] [ -s ] [ -Tterm ] [ -x ] [ -m mac ] [ -V ] [ -Q ] [ file ... ]
DESCRIPTION
Roffbib prints out all records in a bibliographic database, in bibliography format rather than as footnotes or endnotes. Generally it is
used in conjunction with sortbib:
sortbib database | roffbib
Roffbib accepts most of the options understood by nroff(1), most importantly the -T flag to specify terminal type.
If abstracts or comments are entered following the %X field key, roffbib will format them into paragraphs for an annotated bibliography.
Several %X fields may be given if several annotation paragraphs are desired. The -x flag will suppress the printing of these abstracts.
A user-defined set of macros may be specified after the -m option. There should be a space between the -m and the macro filename. This
set of macros will replace the ones defined in /usr/share/tmac/tmac.bib. The -V flag will send output to the Versatec; the -Q flag will
queue output for the phototypesetter.
Four command-line registers control formatting style of the bibliography, much like the number registers of ms(7). The command-line argu-
ment -rN1 will number the references starting at one (1). The flag -rV2 will double space the bibliography, while -rV1 will double space
references but single space annotation paragraphs. The line length can be changed from the default 6.5 inches to 6 inches with the -rL6i
argument, and the page offset can be set from the default of 0 to one inch by specifying -rO1i (capital O, not zero). Note: with the -V
and -Q flags the default page offset is already one inch.
