    <p>Shell running a script is always non interactive shell. You may force to run the script in interactive mode using '-i' option:</p> <p>Try to change:</p> <pre><code>#!/bin/bash </code></pre> <p>to:</p> <pre><code>#!/bin/bash -i </code></pre> <p>see INVOCATION section in 'man bash' (bash.bashrc is where your PS1 is defined):</p> <pre><code> When an interactive shell that is not a login shell is started, bash reads and executes commands from /etc/bash.bashrc and ~/.bashrc, if these files exist. This may be inhibited by using the --norc option. The --rcfile file option will force bash to read and execute commands from file instead of /etc/bash.bashrc and ~/.bashrc. When bash is started non-interactively, to run a shell script, for example, it looks for the variable BASH_ENV in the environment, expands its value if it appears there, and uses the expanded value as the name of a file to read and execute. Bash behaves as if the following command were executed: if [ -n "$BASH_ENV" ]; then . "$BASH_ENV"; fi but the value of the PATH variable is not used to search for the file name. </code></pre> <p>you can also read: <a href="http://tldp.org/LDP/abs/html/intandnonint.html" rel="nofollow">http://tldp.org/LDP/abs/html/intandnonint.html</a></p> <p>simple test:</p> <pre><code>$ cat &gt; test.sh echo "PS1: $PS1" $ ./test.sh PS1: $ cat &gt; test.sh #!/bin/bash -i echo "PS1: $PS1" $ ./test.sh PS1: ${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[01;34m\] \w \$\[\033[00m\] </code></pre>

    1. COThanks wisent, I only changed the first line as you said, left the rest script untouched , and it worked! It seems that there was something special about $PS1 and $PS2 , but not $PS4 , and my script was generally OK as long as it comes to variables expansion.How much detail is there on those things!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
