Give all those pictures the same name format, trailing zeros please for the right order, offset to merge different collections of pictures

When you have different digital cameras, different people, friends and you want to merge all those pictures together, then you get files with same names or files with 3 and 4 digit numbers etc. The result is a mess if you copy it together into one directory.

But if you can add an offset to the picture number and set the number of leading zeros in the file name's number then you can manage.

OFFS != 0 and LZ the same as the files currently have is not supported. Or left as an exercise, hoho ;)

I love NF="${NF/#+(0)/}",it looks like a magic bash spell.

Use a variable in a find command. Useful in scripting.

You define your variable MYVAR with the desired search pattern:

MYVAR=

...which can then be searched with the find command.

This is useful if you in a script, where you want the arguments to be fed into the find command.

The provided search is case insensitive (-iname) and will find all files and directories with the pattern MYVAR (not exact matches). This may go without saying, but if you want exact matches remove the \* and if you want case sensitive, use the -name argument.

Automagically update grub.conf labels after installing a new kernel

I like to label my grub boot options with the correct kernel version/build.

After building and installing a new kernel with "make install" I had to edit my grub.conf by hand.

To avoid this, I've decided to write this little command line to:

1. read the version/build part of the filename to which the kernel symlinks point

2. replace the first label lines of grub.conf

grub.conf label lines must be in this format:

Latest [{name}-{version/build}]

Old [{name}-{version/build}]

only the {version/build} part is substituted.

For instance:

title Latest [GNU/Linux-2.6.31-gentoo-r10.201003]

would turn to

title Latest [GNU/Linux-2.6.32-gentoo-r7.201004]"
