I am trying to locate a file or files with specific data in them. Problem is the file(s) could reside in any one of many directories.
My question is. Is there a way of recursively greping directories for the file(s) with the data I am looking for.
I have tried -

Hi! Suppose I have a directory (no symbolic links) called /WORK that contains 3 subdirectories:
/A
/B
/C
My problem is this: I want to look for a file that contains an order number. So far, I obtain what I want by doing this
/home/acb% cd /WORK/A
/home/acb/WORK/A% grep '093023553' *.*... (3 Replies)
Hello all ( again )
I will like to search and replace string in text file
ok I can loop throw the files like :
foreach f ( ` find . -name "*."`)
.. but here I like to examine the file if in contain the desired string
and so do the sed -e 's/blah/foo/g' thingy on it or there is better way... (1 Reply)
Hello,
First time post - I have no formal unix training and could use some help with this. I have a list of strings in File1 that I want to use to do a recursive search (grep) under a specific directory.
Here is an example of the string I need to search:

I'm using this command to get a recursive grep
find . -name *.i -exec grep 'blah blah' {} \; -exec ls {} \;
now I would like to obtain just the list of the files and not also the line of the file.
How should I change the syntax?
thank you, (5 Replies)
When finding a string in files within a directory, one can use this:
grep -r "searchstring" dir/subdir/ > listofoccurrences.txt
For brevity sake one can enter the intended directory and use this:
grep -r "searchstring" . > listofoccurrences.txt
which as I found out leads to an endless loop,... (2 Replies)
Hi,
on AIX 6.1 , in man document for grep :
-r
Searches directories recursively. By default, links to directories are followed.
But when I use :
oracle@XXX:/appli/XXX_SCRIPTS#grep -r subject *.sh
It returns nothing.
However I have at least one row in a file :

Tricky one:
I want to do several things all at once to blow away a directory (rm -rf <dir>)
1) I want to find all files recursively that have a specific file extension (.ver) for example.
2) Then in that file, I want to grep for an expression ( "sp2" ) for example.
3) Then I want to... (1 Reply)
Can I please have some ideas on how to do a recursive grep with certain types of files? The file types I want to use are *.c and *.java.
I know this normally works with all files.
grep -riI 'scanner' /home/bob/ 2>/dev/null
Just not sure how to get it to work *.c and *.java files. (5 Replies)

mass
mass(3rheolef) rheolef-6.1 mass(3rheolef)NAME
mass -- L2 scalar product
SYNOPSIS
form(const space& V, const space& V, "mass");
form(const space& M, const space& V, "mass");
form (const space& V, const space& V, "mass", const domain& gamma);
form_diag(const space& V, "mass");
DESCRIPTION
Assembly the matrix associated to the L2 scalar product of the finite element space V.
/
|
m(u,v) = | u v dx
|
/ Omega
The V space may be either a P0, P1, P2, bubble, P1d and P1d finite element spaces for building a form see form(2).
The use of quadrature formulae is sometime usefull for building diagonal matrix. These approximate matrix are eay to invert. This proce-
dure is available for P0 and P1 approximations.
Notes that when dealing with discontinuous finite element space, i.e. P0 and P1d, the corresponding mass matrix is block diagonal, and the
inv_mass form may be usefull.
When two different space M and V are supplied, assembly the matrix associated to the projection operator from one finite element space M to
space V.
/
|
m(q,v) = | q v dx
|
/ Omega
for all q in M and v in V.
This form is usefull for instance to convert discontinuous gradient components to a continuous approximation. The transpose operator may
also be usefull to performs the opposite operation.
The following $V$ and $M$ space approximation combinations are supported for the mass form: P0-P1, P0-P1d, P1d-P2, P1-P1d and P1-P2.
EXAMPLE
The following piece of code build the mass matrix associated to the P1 approximation:
geo g("square");
space V(g, "P1");
form m(V, V, "mass");
The use of lumped mass form write also:
form_diag md(V, "mass");
The following piece of code build the projection form:
geo g("square");
space V(g, "P1");
space M(g, "P0");
form m(M, V, "mass");
SCALAR PRODUCT ON THE BOUNDARY
Assembly the matrix associated to the L2 scalar product related to a boundary domain of a mesh and a specified polynomial approximation.
These forms are usefull when defining non-homogeneous Neumann or Robin boundary conditions.
Let W be a space of functions defined on Gamma, a subset of the boundary of the whole domain Omega.
/
|
m(u,v) = | u v dx
|
/ Gamma
for all u, v in W. Let V a space of functions defined on Omega and gamma the trace operator from V into W. For all u in W and v in V:
/
|
mb(u,v) = | u gamma(v) dx
|
/ Gamma
For all u and v in V:
/
|
ab(u,v) = | gamma(u) gamma(v) dx
|
/ Gamma
EXAMPLE
The following piece of code build forms for the P1 approximation, assuming that the mesh contains a domain named boundary:
geo omega ("square");
domain gamma = omega.boundary();
space V (omega, "P1");
space W (omega, gamma, "P1");
form m (W, W, "mass");
form mb (W, V, "mass");
form ab (V, V, "mass", gamma);
