Full Discussion: String replace need help ..
Top Forums Shell Programming and Scripting String replace need help .. Post 302837119 by lohith.dutta on Thursday 25th of July 2013 08:07:47 AM
guys thanks for your quick response, but the problem here is each string contains front slash (/) and I have to replace all the lines through script in couple of servers together

---------- Post updated at 05:37 PM ---------- Previous update was at 04:28 PM ----------

I solved my problem this way ..

awk -F'/' '/mainwh01/ {print $NF}' old-filers | while read filr; do
  sed -i " " "/$filr/s/\/vol\/\(.....\)/\/vol\/oldfiler\/\1/" /etc/fstab

awk -F'/' '/mainwh01/ {print $NF}' /tmp/old-filers | while read filr; do
  sed -i " "   "/$filr/s/\/vol\/\(.....\)/\/vol\/mainwh02\/\1/" /etc/fstab;

I will really appreciate if anyone help me to optimize my logic -- thanks

Each of these functions casts a ray (or rays) through a three-dimensional(3D) data set, then computes and returns the interpolated samples at each step along the way. In trilinear interpolation, the value at point P is computed from its eight surrounding neighbors based on the equation below. P = (1-a)*(1-b)*(1-c)*P0 + a*(1-b)*(1-c)*Px + (1-a)*b*(1-c)*Py + (1-a)*(1-b)*c*Pz + a*b*(1-c)*Pxy + a*(1-b)*c*Pxz + (1-a)*b*c*Pyz + a*b*c*Pxyz where a, b, and c are the fractional parts of the coordinates of point P. The trilinear interpolation is represented by the following figure: Printed copy or displays a figure that represents the trilinear interpolation. In nearest neighbor operation, the sample value at point P is replaced by the value of the nearest neighbor voxel. PARAMETERS
Each of the functions takes the following arguments: rays Casting rays. vol Volume data that consists of slices. buffer Working buffer. RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES
