Hi vc859,

The syntax for 'join' is:

join EXPR,LIST

So your code should be

$variable = join("\n",@variable = <INFILE>);

    Just a small note: Using slurp mode is usually far more efficient than join()ing a temporary array or list.

    $variable=do { local $/=undef; <INFILE> };

    Although the questioner probably does not want to be using join here at all - reading the file via <INFILE> does not remove the file's newlines, so there is probably no need to be adding more.

[hippo]: Corion: Yes, you can. It's all in the pg_hba.conf
[erix]: yeah, but there is a lot SQLite cannot do :)
[hippo]: Database is the 2nd column.
shmem .oO( docker. docker. docker? docker. docker! docker )
[shmem]: at least, some Ook.
[erix]: another simple Pg thing is to running a database off a tsv (alas, readonly)
[erix]: I'm waiting for that zipfile-reading to show up in DBD::SQLite :)
[Corion]: hippo, erix: That sounds promising :)
[Corion]: erix: I misinterpreted that. It only allows to read a zipfile like a table, not reading a database from a zipfile :-(
