Hallo, I want to turn round a datastream with tac, not every line but every sign.
Now my tests: [EMAIL PROTECTED]:~/tmp> echo -e "abbc\ndef" | tac -rs \. fe [EMAIL PROTECTED]:~/tmp> this ist wrong. [EMAIL PROTECTED]:~/tmp> echo -e "abbc\ndef" | tac -rs \[^.\] fed [EMAIL PROTECTED]:~/tmp> this is right but I dont understand how tac interpret the REGEXP because ^ in grep is to negate . When tac the ^ to interpret as linestart then must this also work: [EMAIL PROTECTED]:~/tmp> echo -e "abbc\ndef" | tac -rs \[.^\] abbc def [EMAIL PROTECTED]:~/tmp> it dont work. [EMAIL PROTECTED]:~/tmp> tac --version tac (textutils) 2.1 Written by Jay Lepreau and David MacKenzie. greetings Winfried Münch mailto: [EMAIL PROTECTED] _______________________________________________ Bug-textutils mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/bug-textutils
