What does 'directory=`pwd $1` ' mean, I know pwd is present working directory, so does that command take the present working directory of the directory the user is in depending on the varible ($1)? (2 Replies)
When I use the mv command like say, mv file1 ../, it will move file1 to the parent directory of my current working directory. But where would the file go if I do mv file ... (with 3 periods), where would this move file1? (4 Replies)
$ echo 2 * 3 > 5 is a valid inequality.
This will create a file in the current directory named '5' with the number '2' in it, the names of all the files in the current directory, followed by the number '3' and 'is a valid inequality.'
What I do not understand is why 'is a valid inequality' gets... (2 Replies)
I am going through the Unix Made Easy second edition book by John Muster. So far it's been very informative and I can tell it may be a bit out of date.
In one of the exercises it talks about the "sort" command and using it to sort column's of data etc. The "sort" command has changed a bit and... (1 Reply)
I am scratching my head right now. I am trying to archive a ton of files in a directory. I am attempting to tar them by year. On our development server if I type ls *_2008* it returns all of the files I am expecting to see. (The format of the filename includes xx_xx_xxx_2008-09-29_xxx.xxxx.xxxx)... (8 Replies)
Hi,
can you please tell me what is the purpose of the following line:

basis - polynomial basis
SYNOPSYS
The basis class defines functions that evaluates a polynomial basis and its derivatives on a point. The polynomial basis is designated by a
string, e.g. "P0", "P1", "P2", "bubble",... indicating the basis. The basis depends also of the reference element: triangle, square,
tetrahedron (see reference_element(2)). For instance, on a square, the "P1" string designates the common Q1 four-nodes basis on the refer-
ence square.
The nodes associated to the Lagrange polynomial basis are also available by its associated accessor.
IMPLEMENTATION NOTE
The basis class is a see smart_pointer(2)) class on a basis_rep class that is a pure virtual base class for effective bases, e.g. basis_P1,
basis_P1, etc.
IMPLEMENTATION
