Runpg
(since EVL 2.0)
Run SQL or psql commands from stdin or <f_in>
and write result into stdout or
<f_out>
. It returns output from ‘psql’ as is, so for quering the table to get formatted
EVL output use ‘Readpg’ or ‘evl readpg’.
Password is taken:
- from file ‘$EVL_PASSFILE’, which is by default ‘$HOME/.evlpass’,
- from file ‘$PGPASSFILE’, which is by default ‘$HOME/.pgpass’.
When such file has not permissions 600, it is ignored! For details see ‘evl-password’.
- Runpg
-
is to be used in EVS job structure definition file.
<f_out>
is either output file or flow name. - evl runpg
-
is intended for standalone usage, i.e. to be invoked from command line and writing records to standard output.
EVD and EVS are EVL definition files, for details see evl-evd(5) and evl-evs(5).
