DESCRIPTION
makedbm
takes
infile
and converts it to a pair of files in
dbm.3x
format, namely
outfile.pag
and
outfile.dir.
Each line of the input file is converted to a single
dbm
record.
All characters up to the first tab or space form the key,
and the rest of the line is the data.
If a line ends with \,
then the data for that record is continued on to the next line.
It is left for the clients of the yellow pages to interpret #;
makedbm
does not itself treat it as a comment character.
infile
can be -, in which case standard input is read.
makedbm
is meant to be used in generating
dbm
files for the yellow pages,
and it generates a special entry with the key
yp_last_modified,
which is the date of
infile
(or the current time, if
infile
is -).
OPTIONS
- -i
-
Create a special entry with the key
yp_input_file.
- -o
-
Create a special entry with the key
yp_output_name.
- -d
-
Create a special entry with the key
yp_domain_name.
- -m
-
Create a special entry with the key
yp_master_name.
If no master host name is specified,
yp_master_name
will be set to the local host name.
- -u
-
Undo a
dbm
file.
That is, print out a
dbm
file one entry per line,
with a single space separating keys from values.
EXAMPLE
It is easy to write shell scripts
to convert standard files such as
/etc/passwd
to the key value form used by
makedbm.
For example,
#!/bin/awk -f
BEGIN { FS = ":"; OFS = "\t"; }
{ print $1, $0 }
takes the
/etc/passwd
file and converts it to a form that can be read by
makedbm
to make the yellow pages file
passwd.byname.
That is, the key is a username,
and the value is the remaining line in the
/etc/passwd
file.
