sed or awk to replace a value in a certain line from another file containing a string
Hi experts, In my text file I have the following alot of lines like below. input.k is as follows. Code:
2684717 -194.7050476 64.2345581 150.6500092 0 0 2684718 -213.1575623 62.7032242 150.6500092 0 0 *INCLUDE $# filename ./meshes/exportneu/147.k *END mesh.k is as follows Code:
100 or any other 3 digit number I want to replace the 147.k of this input.k to another number from another file mesh.k which is 100 in this case.. Required output is as follows Code:
2684717 -194.7050476 64.2345581 150.6500092 0 0 2684718 -213.1575623 62.7032242 150.6500092 0 0 *INCLUDE $# filename ../meshes/exportneu/100.k *END I used Code:
sed '/\<meshes\>/!d;=;s/.* ([^ ]\+).*/\1/;R mesh.k' input.k | sed 'N;N;s|\n|s/|;s|\n|/|;s|$|/|;q' >temp.sed sed -i -f temp.sed input.k The point is that I want to replace this Quote:
i know it can work with searching the line with word meshes for example and the dividing with last / and piping the data from other file but am not able to formulate the sed or awk. I hope now you people understand what I mean. regards Last edited by hamnsan; 06-12-2012 at 07:44 AM.. |

Please post the required data from "mesh.k" and "input.k".
Also, please edit your post and use code tags. (hurry up, our mods here, are too fast  ) |

Assuming that mesh.k contains only 1 number: Code:
awk 'NR==FNR{num=$1;next} /[0-9]{1,}\.k$/ {sub("[0-9]{1,}\.k$",num".k")} {print}' mesh.k input.k |
