Hello friends ,

I need help with sed .

echo "/c/dumc"

when i do echo i would like to change the first "c" to d with sed and this change should not effect the "c" which is in dumc and the output should be

d/dumc.

thanks,
venky

echo "/c/dumc" | sed s.c.d.

You were likely thinking of the familiar / which I prefer. There are a few other options.

Code:

echo "/c/dumc" | sed s/c/d/
/d/dumc

echo "/c/dumc" | sed s.c.d.
/d/dumc

echo "/c/dumc" | sed s,c,d,
/d/dumc

echo "/c/dumc" | sed s-c-d-
/d/dumc

echo "/c/dumc" | sed s=c=d=
/d/dumc

echo "/c/dumc" | sed s[c[d[
/d/dumc

echo "/c/dumc" | sed s~c~d~
/d/dumc

echo "/c/dumc" | sed s:c:d:
/d/dumc
