Re: [9fans] Corrupted file entry on QEMU - how to recover?

[Pietro Gagliardi <pietro10@mac.com>]

That part was missing some lines, so I decided to start over. This  
time, an AWK script is used:

	awk '
	/^fn unt[gb]z/ { p(); next; pr(); }
	/^fn df/ { pr(); next; pr(); }
	/^\.C$/ { pr() }
	function pr() { print NR, $0 }' hd.raw

untgz and untbz are functions that extract .tar.gz/.tgz  
and .tar.bz2/.tbz files automatically. df shows the disk usage. .C is  
the macro in my book for a chapter (one of the lines that was  
missing). I tell AWK to print the multi-line functions (with line  
numbers).
