<Idle247> ok
<newbie77> the default softbs (block size for copy operation) is 64k
<Idle247> I dont know how dd_rescue does it
<newbie77> I should have written "frequency of fsny calls on outfile" instead of "sync frequency". Does that make a difference?
<newbie77> fsync
<Idle247> no
<tiGbx> when im trying to compare variable size, using ${#var}, its not working.. :(
<bougyman> -eq
<Idle247> tiGbx: if [ "${#var}" -eq "${#var2}" ];
<Idle247> == is for strings, counter intuitively
<tiGbx> im using -le
<Idle247> whats the line
<tiGbx> var=20; until [ ${#var} -le 8 ] do blahblah
<tiGbx> its not going into my do
<bougyman> huh?
<Pastr> huh yourself
<bougyman> var=four;var2=five;[ ${#var} -eq ${#var2} ] && echo Yes
<Idle247> cause ${#var} == 2
<Idle247> ${var} == 20
<Idle247> ${#var} is the string length
<tiGbx> oh crap
<newbie77> Idle247: wif you read the beginning of www.garloff.de/kurt/linux/ddrescue/, do you understand how it does it?
<Idle247> kinda busy
<tiGbx> thanks yalls
<newbie77> Idle247: sorry for so many questions.
<Idle247> :P
<newbie77> But I feel that we are close to solve the issue :-)
<Idle247> you should not use conv= at all
<Idle247> if you want a raw raw raw copy
<Idle247> of course, noerror helps
<newbie77> did you access the link above?
<Idle247> no
<newbie77> may I please ask you to just read the beginning?
<tiGbx> can you do and/or conditionals in bash?
<Idle247> tiGbx: yes
<tiGbx> pipe?
<Idle247> if [ test ] || [ othertest ]
<Idle247> && as well
<tiGbx> ahh double pipes
<Idle247> newbie77: looks like dd will work just fine
<Idle247> standard dd, to restore
<tiGbx> oh, brackets around each section?
<Idle247> tiGbx: yes
<Idle247> as its 2 seperate instances of 'test'
<Idle247> I think 'test' may support internal ands
<Idle247> -a
<Idle247> and -o
<Idle247> if [ test -o othertest ]
<Idle247> man test
<tiGbx> cool
<newbie77> Idle247: so you had a look at the website? (sorry for asking this, but the data is very important)
<Idle247> newbie77: keep that data file, and dd it to another disk...
<Idle247> or copy, then mount the 'image'
<newbie77> but did you read the beginning of that webpage about dd_rescue??
<zoibergus> hi.. is there any reason this wouldn't work: i have windows and want to test linux on a root partition .. i install and it works, so i delete the windows, move the root partition and create a swap and home and go on with life
<Idle247> YES
<Idle247> its just a raw copy, ffs
<Idle247> zoibergus: bootloader
<Idle247> reinstall it
<zoibergus> but other than that i should be okay?
<Idle247> and depends how you move it
<zoibergus> what do you mean?
<newbie77> Idle247: Thank you very very much!!
<Idle247> :)
<howto> :-)
<Idle247> zoibergus: if you just change the partition start, wont work
<Idle247> if you actually move the data, then it will
<Idle247> you cant just move a partition
<zoibergus> if i use gparted or something?
<zoibergus> or even partition magic?
<Idle247> I personally like cp -rp, since I can use unmatched sizes
<Idle247> no
<Idle247> partition magic wont move the data around
<Idle247> honestly, leave your root partition alone
<Idle247> use that now free space, or 'windows' partition, and just make that a new /home, or similar
<Idle247> or make a lvs, to combine it with an existing drive
<newbie77> can cp copy partitions too?
<Idle247> not really
<zoibergus> how big should i make my root partition? like 5 gigs?
<Idle247> should be enough, yes
<Idle247> depending tho
<zoibergus> just for a simple laptop .. only planning on having root swap and /home
<Idle247> if you start filling it with a complete install, youll have issues
<newbie77> when you say "not really", does that mean "no", or "usually no, but sometimes maybe yes"? (please understand that I learned English late :-)
<Idle247> I generally just do a /, no swap, just a swapfile
<Waterman> whats a swap file?
<Idle247> newbie77: I mean, it can copy the data, if your very careful
<Idle247> but, generally, no, dont do it, ever
<newbie77> thanks
<Idle247> Waterman: use a swap file, instead of a partition
<zoibergus> Idle247 is there any performance difference?
<Idle247> like, /swapfile, then add it to fsta
<Idle247> b
<Idle247> zoibergus: I dont see any
<Idle247> rarely do you ever touch swap
<zoibergus> oh so there's really no point to it then
<Waterman> Idle247, which means u dont have to create a swap partition you can use swap space that is created on / for example?
<Idle247> 15:31:47 up 374 days, 15:45, 1 user, load average: 0.13, 0.03, 0.01
<Idle247> woooohooo
<Idle247> Waterman: which also allows you to change the size :D
<Waterman> hm
<Waterman> how do you create that?
<Idle247> dd if=/dev/zero of=/swapfile
<Idle247> mkswap /swapfile
<Idle247> swapon /swapfile
<Waterman> nice
<Idle247> add it to fstab
<Waterman> thx
<zoibergus> interesting
<Waterman> i know
<Waterman> :)
<zoibergus> adds a lot of flexibility
<Waterman> 257 mb
<Waterman> :D
<Waterman> enough
<howto> :)
<Waterman> so its reserved space for swap
<Waterman> it i understand
<Waterman> just like partition
<Waterman> empty space that is located on /
<Waterman> if*
<Idle247> :D
<Waterman> ?
<Idle247> yea
<Waterman> nice..
<Idle247> I hate seetting aside space for anything
<Waterman> me too
<Waterman> this is good
<Waterman> it works
<Waterman> /swapfile swap swap defaults 0 0
<Waterman> itd my fstab line , looks fine?
<Idle247> yea
<Waterman> nice :)
<Waterman> i have 1 gb of ram
<Waterman> 256mb swap should be enough
<Waterman> :D
<Waterman> 245*
<Trengo> Waterman i'd set the same amount
<Waterman> :D
<Waterman> hehe
<howto> :o)
<Waterman> this is good
<Trengo> in the good old days it was 2.5 times your core
<Idle247> I use 19mb swap, on 160mb ram
<Waterman> yes
<Waterman> 19?
<Idle247> yea
<Waterman> as far as i remember using red hat 6.0
<Idle247> its been running for over a year
<Waterman> 32mb ram -> 64 mb swap
