Creating an entry for /etc/passwd
given an input file containing fields seperated by "," how do I retrieve information of these fields, do some work on them, then create a new input to the etc/passwd file?
someone told me to look at the "sed" command but I still cant seem to get over this problem. I want to work on the data so its not just substituting "," with ":" also, how do I retrieve the first letter of a word and convert it to lower case? thanks. |
