Slight change.
Within "ksh" this should catch virtually every way of invoking the script (including ./scriptname and through $PATH ) and return an absolute path to the script.
However if the script is invoked with a path containing "." or ".." the result of the whence still contains those characters.
Finding a clean path to the script itself involves cleaning up the result of "whence".
One tortuous way is to:
1) Find the inode number of the script (extract from "ls -id").
2) User "dirname" to extract the path to the script,
"cd" to the directory containing the script,
and then store the result of "pwd -P".
The "-P" switch to "pwd" eliminates the effect of links.
The "pwd" also eliminates "." and ".." from the middle of the directory name.
3) Finally use "find" from the stored "pwd -P" with -xdev and -inum switches
to find the raw path to the script.
I'm finally about to make the jump from PHP's mysql driver to the newer mysqli one using the mysqli converter tool.
The tool is called by this command line:
php /usr/share/nginx/html/rather/converter/cli.php -d -p ".php,.shtml,.inc" -u -b -v -w >> /tmp/convert.log

Hi,
This is a quick one.
I have got a review comment in one of the scripts that i wrote:
"In UNIX script it not advisable to use cd to a directory and then run command."
Is this true?
I was trying to cd to log directory and use some cat or head or ls command.
Many Thanks,
