In PostgeSQL's psql interactive terminal, you can type
<enter> to produce a overview that shows a list of common commands. In Ubuntu Linux, is there a way that I can pipe that content to a file that I can
cat or open up in a GUI text editor?
$ echo '\?' | psql > psql_backslash_help.txt $ head psql_backslash_help.txt General \copyright show PostgreSQL usage and distribution terms \crosstabview [COLUMNS] execute query and display results in crosstab \errverbose show most recent error message at maximum verbosity \g [(OPTIONS)] [FILE] execute query (and send results to file or |pipe); \g with no arguments is equivalent to a semicolon \gdesc describe result of query, without executing it \gexec execute query, then execute each value in its result \gset [PREFIX] execute query and store results in psql variables \gx [(OPTIONS)] [FILE] as \g, but forces expanded output mode
