Hi all, Need some help with sed: I have a txt file that contains some 15000 lines, where i want to bring in some structure. First is to replace the first (only the first) space in the line with a <TAB>. After that I want to delete a given number of characters that always begin with the same sequence, but may have different contents. Beginning is always the same, and length to delete is also always the same. I used sed 's/^ /\t/' txtfile, but I do not get a tab. Besides, this might do more then just the first space, I guess. Could someone shed some more light here? -- L. de Braal BraHa Systems NL - Terneuzen T +31 115 649333 F +31 115 649444 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
