Have a directory "dir/", containing the files "a", "b" and "c", possibly more.
Each file is filled with key=value lines.
Is there an elegant way to source all the files in "dir/" into environment
variables of key=value, without writing to a temporary file and sourcing that at the end?
"cat * | envfile -" ?
The problem you'll need to solve is this one:
If "a" and "b" both contain the same key, the value in "b" should overwrite that in
"a", but that is probably immanent anyway.
If you have duplicates, you'll want to determine a sorting order for
the files. If you're happy with regular alphanumeric sorting, then
something like this should work (untested)
(using a loop instead of elglob because cat * won't behave correctly
if dir is empty)
#!/bin/execlineb
importas dir 1
shift
elgetpositionals
emptyenv -c
pipeline
{
forbacktickx -E -d"\n" file { ls -1 ${dir} }
cat ${dir}/${file}
}
envfile -
$@
