Scripts and Code Snippits

A collection of scripts and code snippits I’ve written to help me do stuff.

I’ll add to this page as I go. I’m not going to try and back-post every little nifty thing I’ve ever written!

Linux Bash

line count:wc -l `find . -name "*.[ch]" -print` | tail -1 | awk '{print $1}'

Nifty Maven Bits

dependency:sources to get once-off sources for all your dependencies instead of telling m2eclipse to get sources. This avoides constant re-trying to get sources that don’t exist (that can take ages).

Groovy

Unfortunately the WordPress formatter doesn’t support Groovy yet. Closest you can get is Java.

generateTestSuite.groovy

Reads in the list of files in the current directory and creates a Selenese test suite script. Intended to gather together Selenese tests into a suite.

I don’t use this script anymore as I prefer using Selenium through Selenium Remote Control.

writer = new File("test.html").newWriter()
writer.writeLine("
<table><tbody>
<tr>
<td><a href="${fn}" target="testFrame">${fn}</a></td>
</tr>
</tbody></table>
")
writer.close()

Oracle

Enable and disable triggers in Oracle

ALTER TRIGGER trigger_name DISABLE;
ALTER TRIGGER trigger_name ENABLE;

Analyse Oracle lock states

select * from dba_blockers;
ALTER SYSTEM KILL SESSION 'sid,serial#' IMMEDIATE;

SELECT s.sid,
s.serial#,
s.osuser,

FROM   v$session s
WHERE s.sid in (34,10,39);

ALTER SYSTEM KILL SESSION '10,1688' IMMEDIATE;
ALTER SYSTEM KILL SESSION '34,19649' IMMEDIATE;
ALTER SYSTEM KILL SESSION '39,19948' IMMEDIATE;

Various other little bits I haven’t properly categorised yet.

sed magic

sed command to insert toDate() fuction into sample data build script:

cat db2_sample_data.sql | sed "s| '[-0-9]\+'| to_date\(&, 'yyyy-mm-dd')|g" | sed "s|'[-0-9]\+ [0-9\:\.]\+'| to_date\(&, 'yyyy-mm-dd hh24:mi:ss.ms')|g" > result.sql

cat db2_sample_data.sql | sed "s| '[-0-9]\+'| to_date\(&, 'yyyy-mm-dd')|g" | sed "s|'[-0-9]\+ [0-9\:\.]\+'| to_date\(
&, 'yyyy-mm-dd hh24:mi:ss')|g" | sed "s|.0'|'|g" > result.sql
