+NAME
+ dbf2sql - Insert xBase-style .dbf-files into a Post-
+ greSQL-table
+
+SYNOPSIS
+ "dbf2pg [options] dbf-file"
+ Options:
+ [-v[v]] [-f] [-u | -l] [-c | -D] [-d database] [-t table]
+ [-h host] [-s oldname=newname[,oldname=newname]] [-s
+ start] [-e end] [-W] [-U username] [-B transaction_size]
+ [-F charset_from [-T charset_to]]
+
+
+DESCRIPTION
+ This manual page documents the program dbf2pg. It takes
+ an xBase-style .dbf-file, and inserts it into the speci-
+ fied database and table.
+
+ OPTIONS
+ -v Display some status-messages.
+
+ -vv Also display progress.
+
+ -f Convert all field-names from the .dbf-file to low-
+ ercase.
+
+ -u Convert the contents of all fields to uppercase.
+
+ -l Convert the contents of all fields to lowercase.
+
+ -c Create the table specified with -t. If this table
+ already exists, first DROP it.
+
+ -D Delete the contents of the table specified with -t.
+ Note that this table has to exists. An error is
+ returned if this is not the case.
+
+ -W Ask for password.
+
+ -d database
+ Specify the database to use. An error is returned
+ if this database does not exists. Default is
+ "test".
+
+ -t table
+ Specify the table to insert in. An error is
+ returned if this table does not exists. Default is
+ "test".
+
+ -h host
+ Specify the host to which to connect. Default is
+ "localhost".
+
+
+
+
+
+ 1
+
+
+
+
+
+dbf2sql(1L) dbf2sql(1L)
+
+
+ -s oldname=newname[,oldname=newname]
+ Change the name of a field from oldname to newname.
+ This is mainly used to avoid using reserved SQL-
+ keywords. Example:
+ -s SELECT=SEL,COMMIT=doit
+ This is done before the -f operator has taken
+ effect!
+
+ -s start
+ Specify the first record-number in the xBase-file
+ we will insert.
+
+ -e end Specify the last record-number in the xBase-file we
+ will insert.
+
+ -B transaction_size
+ Specify the number of records per transaction,
+ default is all records.
+
+ -U username
+ Log as the specified user in the database.
+
+ -F charset_from
+ If specified, it converts the data from the speci-
+ fied charset. Example:
+ -F IBM437
+ Consult your system documentation to see the con-
+ vertions available.
+
+ -T charset_to
+ Together with -F charset_from , it converts the
+ data to the specified charset. Default is
+ "ISO-8859-1".
+
+ENVIRONMENT
+ This program is affected by the environment-variables as
+ used by "PostgresSQL." See the documentation of Post-
+ gresSQL for more info.
+
+BUGS
+ Fields larger than 8192 characters are not supported and
+ could break the program.
+ Some charset convertions could cause the output to be
+ larger than the input and could break the program.

+.SH NAME
+dbf2sql \- Insert xBase\-style .dbf\-files into a PostgreSQL\-table
+.SH SYNOPSIS
+.B dbf2pg [options] dbf-file
+.br
+.br
+Options:
+.br
+[-v[v]] [-f] [-u | -l] [-c | -D] [-d database] [-t table]
+[-h host] [-s oldname=newname[,oldname=newname]]
+[-s start] [-e end] [-W] [-U username] [-B transaction_size]
+[-F charset_from [-T charset_to]]
+
+.SH DESCRIPTION
+This manual page documents the program
+.BR dbf2pg.
+It takes an xBase-style .dbf-file, and inserts it into the specified
+database and table.
+.SS OPTIONS
+.TP
+.I "\-v"
+Display some status-messages.
+.TP
+.I "-vv"
+Also display progress.
+.TP
+.I "-f"
+Convert all field-names from the .dbf-file to lowercase.
+.TP
+.I "-u"
+Convert the contents of all fields to uppercase.
+.TP
+.I "-l"
+Convert the contents of all fields to lowercase.
+.TP
+.I "-c"
+Create the table specified with
+.IR \-t .
+If this table already exists, first
+.BR DROP
+it.
+.TP
+.I "-D"
+Delete the contents of the table specified with
+.IR \-t .
+Note that this table has to exists. An error is returned if this is not the
+case.
+.TP
+.I "-W"
+Ask for password.
+.TP
+.I "-d database"
+Specify the database to use. An error is returned if this database does not
+exists. Default is "test".
+.TP
+.I "-t table"
+Specify the table to insert in. An error is returned if this table does not
+exists. Default is "test".
+.TP
+.I "-h host"
+Specify the host to which to connect. Default is "localhost".
+.TP
+.I "-s oldname=newname[,oldname=newname]"
+Change the name of a field from
+.BR oldname
+to
+.BR newname .
+This is mainly used to avoid using reserved SQL-keywords. Example:
+.br
+.br
+-s SELECT=SEL,COMMIT=doit
+.br
+.br
+This is done
+.BR before
+the
+.IR -f
+operator has taken effect!
+.TP
+.I "-s start"
+Specify the first record-number in the xBase-file we will insert.
+.TP
+.I "-e end"
+Specify the last record-number in the xBase-file we will insert.
+.TP
+.I "-B transaction_size"
+Specify the number of records per transaction, default is all records.
+.TP
+.I "-U username"
+Log as the specified user in the database.
+.TP
+.I "-F charset_from"
+If specified, it converts the data from the specified charset. Example:
+.br
+.br
+-F IBM437
+.br
+.br
+Consult your system documentation to see the convertions available.
+.TP
+.I "-T charset_to"
+Together with
+.I "-F charset_from"
+, it converts the data to the specified charset. Default is "ISO-8859-1".
+.SH ENVIRONMENT
+This program is affected by the environment-variables as used
+by
+.B PostgresSQL.
+See the documentation of PostgresSQL for more info.
+.SH BUGS
+Fields larger than 8192 characters are not supported and could break the
+program.
+.br
+Some charset convertions could cause the output to be larger than the input
+and could break the program.
