    <p>I am running a jar file from within an app bundle on Mac OS X Leopard. I need to pass into the jar a parameter. The parameter is the absolute path of the file which called the app bundle. I have my short bash script below. I know $0 gives the absolute path to the app bundle itself. </p> <p>Does anyone know how to store in a variable the path I need (CALLERPATH below)? The current script listed works fine if another script calls it (find caller script in the reply from Dennis), but does not work the same when I double-click on "file.xyz".</p> <p>Script 1</p> <pre><code>#!/bin/bash echo $0 echo $_ echo $(dirname $0) echo $(basename $0) echo $PWD echo "$@" echo $PPID echo "My PPID echo" myPPID=$PPID echo $(ps -p $myPPID -o args=) BASEDIR=`dirname "$0"` echo "CallerPath Output 1" callerpath="$(/bin/ps -p $PPID -o args=)" echo -e "$callerpath\n" echo "Caller Path Output 2" callerpath="${callerpath#/bin/bash *}" echo -e "$callerpath\n" echo "Final Caller Path" callerpath="${callerpath%/*}" echo -e "$callerpath\n" exec java \ -jar "$BASEDIR/../Resources/Java/myJar.jar" "$callerpath" </code></pre> <p>Output 1</p> <pre><code>9/25/09 3:54:42 PM [0x0-0xbb0bb].MyApp[1496] /Applications/appBundle.app/Contents/MacOS/myScript 9/25/09 3:54:42 PM [0x0-0xbb0bb].MyApp[1496] /Applications/appBundle.app/Contents/MacOS/myScript 9/25/09 3:54:42 PM [0x0-0xbb0bb].MyApp[1496] /Applications/appBundle.app/Contents/MacOS 9/25/09 3:54:42 PM [0x0-0xbb0bb].MyApp[1496] myScript 9/25/09 3:54:42 PM [0x0-0xbb0bb].MyApp[1496] / 9/25/09 3:54:42 PM [0x0-0xbb0bb].MyApp[1496] -psn_0_766139 9/25/09 3:54:42 PM [0x0-0xbb0bb].MyApp[1496] 63 9/25/09 3:54:42 PM [0x0-0xbb0bb].MyApp[1496] My PPID echo 9/25/09 3:54:42 PM [0x0-0xbb0bb].MyApp[1496] ps: Invalid process id: -o 9/25/09 3:54:42 PM [0x0-0xbb0bb].MyApp[1496] ps: illegal argument: args= 9/25/09 3:54:42 PM [0x0-0xbb0bb].MyApp[1496] usage: ps [-AaCcEefhjlMmrSTvwXx] [-O fmt | -o fmt] [-G gid[,gid...]] 9/25/09 3:54:42 PM [0x0-0xbb0bb].MyApp[1496] [-g grp[,grp...]] [-u [uid,uid...]] 9/25/09 3:54:42 PM [0x0-0xbb0bb].MyApp[1496] [-p pid[,pid...]] [-t tty[,tty...]] [-U user[,user...]] 9/25/09 3:54:42 PM [0x0-0xbb0bb].MyApp[1496] ps [-L] 9/25/09 3:54:42 PM [0x0-0xbb0bb].MyApp[1496] CallerPath Output 1 9/25/09 3:54:42 PM [0x0-0xbb0bb].MyApp[1496] Caller Path Output 2 9/25/09 3:54:42 PM [0x0-0xbb0bb].MyApp[1496] Final Caller Path </code></pre> <p>Script 2</p> <pre><code>#!/bin/bash echo $0 echo $_ echo $(dirname $0) echo $(basename $0) echo $PWD echo "$@" echo $PPID echo "My PPID export" export myPPID=$PPID echo $(ps -p $myPPID -o args=) BASEDIR=`dirname "$0"` echo "CallerPath Output 1" callerpath="$(/bin/ps -p $PPID -o args=)" echo -e "$callerpath\n" echo "Caller Path Output 2" callerpath="${callerpath#/bin/bash *}" echo -e "$callerpath\n" echo "Final Caller Path" callerpath="${callerpath%/*}" echo -e "$callerpath\n" exec java \ -jar "$BASEDIR/../Resources/Java/myJar.jar" "$callerpath" </code></pre> <p>Output 2</p> <pre><code>9/25/09 4:02:40 PM [0x0-0xc10c1].MyApp[1561] /Applications/appBundle.app/Contents/MacOS/myScript 9/25/09 4:02:40 PM [0x0-0xc10c1].MyApp[1561] /Applications/appBundle.app/Contents/MacOS/myScript 9/25/09 4:02:40 PM [0x0-0xc10c1].MyApp[1561] /Applications/appBundle.app/Contents/MacOS 9/25/09 4:02:40 PM [0x0-0xc10c1].MyApp[1561] myScript 9/25/09 4:02:40 PM [0x0-0xc10c1].MyApp[1561] / 9/25/09 4:02:40 PM [0x0-0xc10c1].MyApp[1561] -psn_0_790721 9/25/09 4:02:40 PM [0x0-0xc10c1].MyApp[1561] 63 9/25/09 4:02:40 PM [0x0-0xc10c1].MyApp[1561] My PPID export 9/25/09 4:02:40 PM [0x0-0xc10c1].MyApp[1561] CallerPath Output 1 9/25/09 4:02:40 PM [0x0-0xc10c1].MyApp[1561] Caller Path Output 2 9/25/09 4:02:40 PM [0x0-0xc10c1].MyApp[1561] Final Caller Path </code></pre>

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).
