Full Discussion: awk Replace Multiple patterns within a list_file with One in target_file
Top Forums UNIX for Beginners Questions & Answers awk Replace Multiple patterns within a list_file with One in target_file Post 303009771 by mpvphd on Tuesday 19th of December 2017 02:41:32 PM
Old 12-19-2017
I am trying to send a regex with pipes to do a
'pattern OR pattern OR ...'
with 'pattern | pattern | ...'

for example with one replacement :
Code:
echo 'toto; tutu | tata | tonton | titi ' | awk '{gsub(/ tutu | tata | tonton | titi /," toto ")}1'
gives 
toto; toto | toto | toto | toto

with
Code:
awk -F';' 'NR==FNR{A[$1]=$2; next} IGNORECASE = 1 {for(i in A) gsub(/A[i]/,i)}1’

I expect to :
1 ) register an array A with $2 as content and $1 as key
so in the fist line
$2 =' tutu | tata | tonton | titi '
$1 = ' toto '
2 ) replace with gsub(/$2/,$1)}1
so in the fist line
awk 'IGNORECASE = 1 {gsub(/ tutu | tata | tonton | titi /," toto ")}1

actualy i am looking to -f option
Is that a good idea ?
I am thinking about doing
Code:
BEGIN
{replacing command 1}
{replacing command 2}
etc.
END

What coold I do ?

msh2geo

msh2geo(1rheolef)						    rheolef-6.1 						 msh2geo(1rheolef)

NAME

       msh2geo - convert gmsh mesh in geo format

SYNOPSIS

	 msh2geo [-zr|-rz] input[.msh] > output.geo

DESCRIPTION

       Convert	a  gmsh `.msh' into `.geo' one.  The output goes to standart output.  See the gmsh documentation for a detailed description of the
       `.mshcad' input file for gmsh.

EXAMPLES

	 gmsh -2 toto.mshcad -o toto.msh
	 msh2geo toto.msh > toto.geo

	 gmsh -2 -order 2 toto.mshcad -o toto2.msh
	 msh2geo toto2.msh > toto2.geo

COORDINATE SYSTEM OPTION

       Most of rheolef codes are coordinate-system independant.  The coordinate system is specified in the geometry file `.geo'.

       -zr

       -rz    the 2d mesh is axisymmetric: zr (resp. rz) stands when the symmetry is related to the first (resp. second) coordinate.

NOTES

       Pk triangle, when k>=5, may have internal nodes renumbered: from the

GMSH DOCUMENTATION

	 The nodes of a curved element are numbered in the following order:

	   the element principal vertices;
	   the internal nodes for each edge;
	   the internal nodes for each face;
	   the volume internal nodes.

	 The numbering for face and volume internal nodes is recursive,
	 i.e., the numbering follows that of the nodes of an embedded face/volume.
	 The higher order nodes are assumed to be equispaced on the element.

       In rheolef, internal triangle nodes are numbered from left to right and then from bottom to top. The numbering differ for triangle  when  k
       >= 5.  Thus, msh2geo fix the corresponding internal nodes numbering during the conversion.

       Pk tetrahedrons and hexaedrons in gmsh and rheolef has not the same edge-node order nd orientation.  E.g. for tetrahedrons, edges 13 and 23
       should be swaped and reoriented as 32 and 31.  Thus, msh2geo fix the corresponding internal nodes numbering.

TODO

       Fix for P3-tetra: swap edges orientations for 3,4,5 and swap faces 1 and 2. Check P4(T) for face orientation.  Perform  face  visualisation
       with gnuplot face fill.

       See also hexa edges orient and faces numbers and orient.

       Check  that node are numbered by vertex-node, then edge-node, then face(tri,qua)-node and then volume(T,P,H)-node.  Otherwise, renumber all
       nodes.

       Support for high order >= 6 element ? not documented in gmsh, but gmsh supports it at run
