Need help in SED
Hi,
I am quite new to Bash shell and Unix recently.
I would like to use SED to replace characters in my files.
The input I have is the result of SED which removes all whitespaces which you can see "charc" is from "char c".Assume I have the below input character in my file:-
addstr(c,outset,j,maxset){
charc;
char*outset;
int*j;
}
I wanted to tokenise "*", "," and ";" as one separate token respectively let say a character "s" each time it is seen. And for other characters I would like to tokenize to character "t". FOr the () and { } I would also like to tokenize as one character "s".While for char, int or str type, I would like to replace with "d" as one group.
The output I am looking after is:-
ttttttststtttttststtttttss
dts
dstttttts
dsts
And then I plan to count the number of t,s,and d for each line.
I tried to find information on SED tutorials on google but it doesnt detailed to this specific case. Could anyone help.
Appreciate alot.
Thanks.
Rgrds,
Jason
