It is necessary in the bash script to check whether the specified psql database exists or not. Are there any regular funds?

For files there is a construction: if [ -f $FILE ]; then if [ -f $FILE ]; then For psql - maybe there is something of their own. Or maybe you should dig in the direction of the physical search for the database itself in the file format?

    Apparently you need something like this:

     if psql -lqt | cut -d \| -f 1 | grep -qw <db_name>; then #база существует else #база не существует fi

    • Akalnq, yes, this option is almost suitable! The only thing grip with the keys- -qw does not give me anything sensible. If it is completely without keys - it works, but there is no uniqueness) if there are 3 bases a la db_test, db_test1, db_test2 - then on request db_test I will see all three) - Dofri
