<0> Does a single command exist which overwrites a file with only its last <x> lines?
<0> sed -i -e :a -e '$q;N;<lines+1>,$D;ba' <filename>
<1> hey guys, I am trying to find the largest partition based on the output of mac-fdisk /dev/blah would you guys help me with the sed command? here is the output http://keanmarine.com/cool and I have something like mac-fdisk -l /dev/hda | sed '1,6d' | sed 's/\*/ /' | sort -k 4 -g | tail -n 1 | gawk '{print $1}'
<1> but im not sure if that will produce the largest partition every time
<1> any one have any idea?
<1> thanks, i will be around if anyone catches this:)
<2> hi all
<2> I want to print all lines of a files except those which contain INET
<2> and want to repace tcp TCP which comes after the line containing INET
<2> any idaes how?
<3> payal: sed -n '/INET/!p' filename
<4> sed '/INET/d' filename ;)
<3> payal: sed '/INET/{n;s/tcp/TCP/}' filename
<2> was on phone
<4> '/INET/{d;n;s/tcp/TCP/}'
<2> gnubien: sed '/INET/{n;s/tcp/TCP/}' - this prints out line havig INET
<4> payal: '/INET/{d;n;s/tcp/TCP/}'
<2> iSteve: are you sure?
<4> ...
<2> no further processing is done on Deleted line
<2> RIP
<4> I am absolutely positive.
<4> There's the "n" there, too
<4> (viz man sed.)
<2> it does not work
<4> sed --version
<2> GNU sed version 4.1.4
<4> $ echo -e "INET\ntcp" | sed '/INET/{d;n;s/tcp/TCP/}'
<4> tcp
<4> I can with gnu sed 4.1.5
<4> oh crap, I can see the problem now
<2> no no after line is deleted control is p***ed to next line and first command of the script
<2> any ideas anyone?
<4> well
<4> it's easy with -n
<2> how?
<4> sed -n '/INET/ {n; s/tcp/TCP/; p;}'
<4> hmm
<2> nope
<4> uno momento
<2> it prints only one line that after INET
<4> sed -n '/INET/ {n; s/tcp/TCP/;}; /INET/!p'
<4> there, done
<4> (next time provide sample input:)
<2> sorry and thanks a lot
<2> in n; s/tcp/TCP/; ---> is the last ; needed
<4> No. Can't you try out _yourself_?
<2> yes I tried it but was wondering why you gave it
<4> oh I just like to:)
<1> hey guys, do you know a way to make a progress bar for cp -a?
<5> yes. patch cp.
<4> or use rsync or scp ;)
<4> you could also use cp -av and then sed the hell out of the output;)
<5> a progress bar implies you know the value of 100%
<5> which is not even true for cp -a
<5> at the beginning i mean
<4> you can still get some sort of dotbar
<4> which might be enough for our poor user
