Check These Out
This command basically adds up all of the individual instances processes and gives you a grand total for used memory in that instance alone.
Handy when you need to create a list of files to be updated when subversion is not available on the remote host. You can take this tar file, and upload and extract it where you need it. Replace M and N with the revisions specific to yours. Make sure you do this from an updated (svn up) working directory.
Especially useful to gauge the performance of a VPS.
Simple edit to work for OSX.
Now just add this to your ~/.profile and `source ~/.profile`
Encodes HTML entities from input (file or stdin) so it's possible to directly past the result to a blog or HTML source file.
This is an expansion on a previous entry, which I've wrapped in a function and placed in my profile. The "$@" is a positional parameter, much like "$*", but the parameters are passed on intact, without interpretation or expansion; so you can simply call the function like this:
mergepdf *
This will output a merged PDF of all PDFs in the current directory. Alternatively, you can simply list them like so:
mergepdf 00.pdf 01.pdf 02.pdf ...
N.B. Passing a wildcard will merge all PDFs in the current directory in name order, e.g. 00.pdf 01.pdf aa.pdf ab.pdf
Sometimes, you don't want to just replace the spaces in the current folder, but through the whole folder tree - such as your whole music collection, perhaps. Or maybe you want to do some other renaming operation throughout a tree - this command's useful for that, too.
To rename stuff through a whole directory tree, you might expect this to work:
for a in `find . -name '* *'`;do mv -i "$a" ${a// /_};done
No such luck. The "for" command will split its parameters on spaces unless the spaces are escaped, so given a file "foo bar", the above would not try to move the file "foo bar" to "foo_bar" but rather the file "foo" to "foo", and the file "bar" to "bar". Instead, find's -execdir and -depth arguments need to be used, to set a variable to the filename, and rename files within the directory before we rename the directory.
It has to be -execdir and won't work with just -exec - that would try to rename "foo bar/baz quux" to "foo_bar/baz_quux" in one step, rather than going into "foo bar/", changing "baz quux" to "baz_quux", then stepping out and changing "foo bar/" into "foo_bar/".
To rename just files, or just directories, you can put "-type f" or "-type d" after the "-depth" param.
You could probably safely replace the "mv" part of the line with a "rename" command, like rename 'y/ /_/' *, but I haven't tried, since that's way less portable.
