fw2csv

Fixed width data files are probably the most annoying data to import into database.
This utility allows user to insert user-defined column separators into user-defided positions of flat file table given in fixed-width format.
I am using this utility to import astronomical catalogs provided as flat tables at CDS ftp-server into postgresql;

Build:
$ make all [cc={icc|gcc}]

Install:
$ make install [prefix=/path/to/your/bin/directory]

Example of usage:
$ gzip -dc table.dat.gz | fw2csv --stops=4,10,11,20,30,36 -d '|' -header 1 | psql wsdb -c "copy mytable from stdin with csv delimiter '|'"

For the list of available options call
$ fw2csv --help
