<0> how do i use *.diff file to make changes on other file?
<1> use the help of "patch"
<0> heiner, thx, but how do i know what is original file if patch file is named style.diff, and i need it for TinyXml source files?
<2> [cro]smiley: man patch, read -p option and just the description
<3> how can i pull lbl-internal.20050107-1424.port027.dump.anon out of this line: <img src="/icons/unknown.gif" alt="[ ]"> <a href="lbl-internal.20050107-1424.port027.dump.anon">lbl-internal.2005010..></a> 14-Oct-2005 15 29 770
<0> snappy, thx i was looking patch --help. I'm glad you made me read :)
<4> bash newbie, why doesn't this code work:
<4> while [ ! -f "$archive_directory/$file.$i.gz" -o ! -f "$archive_directory/$file.$i" ]; do
<4> ((i++))
<4> done
<4> i'm trying to go through a log archive to find the lowest unused log number
<5> gnychis: depends how persnickety you want to be about it, but I would probably grep -o 'href="[^"]*"' | sed 's/^href="//; s/"$//'
<3> Vasistha: thanks
<4> that code just produces an infinite loop. can $i be used again in the while expression?
<5> phatmonkey: I'm trying to figure out what it is you're trying to do...
<4> i have a directory of log archives number log.0.gz, log.1.gz, and so on
<4> i'm trying to find the lowest available number for the next log archive
<5> phatmonkey: have you considered doing something more like ls log* -v | tail -n 1
<5> phatmonkey: alternately, log* -t would sort by time, which also ought to work
<4> ah, smart
<4> but then if there was a log.0.gz and logfoo.0.gz, surely log*
<4> wait, nm, i'll just do log.*
<4> then how can I add 1 to the integer in the filename?
<5> well, it depends how well-defined your log file names are ... perhaps you want log.*.gz
<5> last_log_num=$(basename ${filename#log.} .gz)
<6> hello
<7> how to check if a file exists regardless of case? if [[ if /file\.txt/i ]]?
<7> s/[[ if/[[ -f/
<8> shopt -s nocasematch && shopt -s nocaseglob
<9> Is there a way to make a <() file to have a specific file extension?
<8> Kuwanger: Write all in an array arr=(<(whatever).extension); echo "${arr[@]}"
<9> WoodyWoodpecker: Uh, how will that help exactly?
<8> You got your extension.
<9> Uh, the file doesn't exist.
<8> You know <() is process redirection. You save the output of this process in an array 'arr' and hang its extension on there.
<10> o_O
<4> Vasistha, last_log_num=$(basename ${filename#log.} .gz) - what is that doing, I don't understand
<10> Kuwanger: i doubt you can make it have an extension, it's 'just' a filedescriptor, those are numeric (iirc)
<9> Knirch: Right. I just sort of hoped that bash offered a way to make a symlink to it or something. Thanks anyways.
<10> use a named pipe
<9> Knirch: Hmm..that's a good idea.
<8> phatmonkey: Strip shortest match of 'log.' from beginning of 'filename' and get the basename(1) of it, after that add .gz to the result. Then ***ign everything to last_log_num.
<5> phatmonkey: well, it takes two steps to get what you want...
<5> phatmonkey: strip off the "log." from the beginning, and strip off the ".gz" from the end
<4> hmm, i don't seem to have basename in my paht
<4> path
<5> phatmonkey: then let's do it a different way, anyway, let's just drop basename entirely
<4> ah, i've found a way that works
<4> while [ "1" ] with an if and a break
<4> not very neat, but it's working
<5> phatmonkey: whatever works for you. using ls | tail will be much faster (especially with a long list), but if performance is not an issue, then whatever's easiest to maintain is best
<4> hmm, you're right actually, performance is a bit of an issue
<4> oh well, the lists aren't going to be big, this'll be fine, thanks for the help
<5> phatmonkey: anyway, if you want to do it the other way: man bash and see the section on parameter expansion. You'll want to do, e.g., last_log_name=$(ls -t | head -n 1); temp=${last_log_name#log.}; last_log_num=${temp%.gz};
<11> from a script----- mv $1 $2.txt . Now should "script-name sometextfile.txt renamed" work?
<11> this gives an error----- mv: target `renamed.txt' is not a directory ..
<12> grizzly: That error messages means that mv received 3 or more arguments, and not just the 2 names you intended.
<12> grizzly: With 3 arguments, mv expects that the last name is a directory, e.g. mv file1 file2 dir1, to move file1 and file2 into dir1.
<12> grizzly: Put a 'set -x' at the top of the script, and run it again to see what is really going on.
<13> How do I run a command stored in a variable?
<13> what? no response?
<13> How do I run a command stored in a variable?
<14> echo $($var)
<13> Thought that was a hack.
<13> rodrickbrown: doesnt work
<15> you can use eval
<16> foo="ls -l"; $foo
<17> kbrooks: it does here. but if you want the output as formated by the command, you should use echo "$($var)"
<15> it's dangerous though.
<13> i dont :-)
<17> actually simply $var as shown by grepper works too.
<18> windoz is so use[r]less
<18> and they call bull**** tech
<18> its smth to trash
<18> wtf
<18> linux is halfways
<18> still

<18> since they dont live, dont speak
<18> all static hertz bull****
<18> all battery tech is bull**** anyway
<18> ill do a teraherz comp, i hope, soon
<18> somebody
<18> brought the idea of computers, electronic, crap, back to this eartch

<18> or http://xmb.ath.cx/code
<18> spam is added to ignore list foo
<18> ignore
<18> like you have anything else4 to do
<19> you obviously don't

<18> joker
<18> damnit how can i forget my icq p***
<18> bored users
<20> hey guys, I'm trying to bind a key combo to a script I wrote, but it's not working. I have a zenity dialogue running from it, and it's just not running when I hit the bound keys.
<21> so first debug your window manager, make sure it tries to launch the script.
<21> or put something into your script that shows that it was run, even if you "see" nothing.
<20> twkm: I'm actually not sure how to do that.
<21> then work outwards from there.
<20> oh wait, I just found out that Control + Shift + P works, but Mod4 (super) + P doesn't
<20> that's weird... Mod4 works in other bindings
<20> I wonder why mod4 won't work for this one binding? wtf...+
<22> y0
<23> I need to write a regular expression for grep that would print everything but commented lines. This includes lines that have zero or more spaces/tabs and then a '#', a '!' or a ';'. I am failing, so can you please help me?
<23> `egrep -vh '^[#!;].*|^[ \t]*[#!;].*' "$@"' --> Not good for lines that have spaces or tabs.
<24> grep -v '^[[:space:]]*[^#!;]' -> untested
<24> egrep
<23> m4n: Thanks, but something's wrong with it.
<24> redondos: tell me
<24> redondos: do you have a sample file ? am lazy to make one :-)
<23> Yes.
