Nano calls it ^L, but of course, typing something like$ grep -v ^\^L filedoesn't work. Its unicode codepoint is 000C. How can I match it in a regular expression?
How can I match the page break character in a regular expression?
grep;regular expression;escape characters
That seems to be the good old form feed character, described in man ascii as:Oct   Dec   Hex   Char------------------------------------------014   12    0C    FF  '\f' (form feed)(Not mentioned there, but ^L's code is the same 12.)Then in bash any of these should work:grep -v $'^\f' filegrep -v $'^\cL' filegrep -v $'\x0C' file
