Answer» Hi EVERYBODY!
I want to change some lines of text with the sed command but not as usual. This are the lines I have:
south
{
type zeroGradient;
}
WEST
{
type zeroGradient;
}
east
{
type zeroGradient;
}
NORTH
{
type zeroGradient;
}
TOP
{
type zeroGradient;
}
}
And these are the lines I want:
south
{
type zeroGradient;
}
west
{
type symmetryPlane;
}
east
{
type symmetryPlane;
}
north
{
type zeroGradient;
}
top
{
type zeroGradient;
}
}
I'm working on CFD simulations and the number of lines depend on the grid... So I can't use: sed -i '22s/zeroGradient/symmetryPlane/g', because it won't be allways at the same line.
What can I do?
Thank you very much for helping me!
RogerYou use awk, not sed
Code: [Select]
awk -vRS="}" '/west|east/{ gsub(/zeroGradient/,"symmetryPlane"); }1' ORS="}" file
