bash

I have a multi-line string coming from another program that I want to convert to a SQL command. I was hoping that printf could help me, but it doesn't seem to work:

echo -e '1\n2\n3'|printf 'SELECT %s INTO MyTable'

I was hoping to see:

SELECT '1
2
3' INTO MyTable

But I got:

SELECT  INTO MyTable

How can I get the %s to read stdin?

But today I notice that bash just opens the program and goes to a new prompt, e.g. me@box:~$… >>> More

First login process name seems to be set to "-bash", but if I subshell then it becomes "bash". for example: root@nowere:~# echo $0 -bash root@nowere:~# bash root@nowere:~# echo $0 bash -bash is causing some scripts to fail, such as . /usr/share/debconf/confmodule exec /usr/share/debconf/frontend… >>> More
