Hello all,


suppose i need to search atom from a group of lines from a file,

for example file is

list
atom [3:0] grant;
ready


here i need to change the 3rd line from "atom [3:0] grant" to "atom [7:0] grant" what is the necessary regular expression to do the above.

i will be helpful if some gives some sought of clue to solve the above

thanks

Thank you microe_victor,

Even i found out a simple expression which changes the given value accordingly.

i.e

regsub {\[3:0\]} $sample3 {[7:0]} sample5

well thanks again!!
