<0> as it works fine, what is wrong with using it?
<1> greycat, ok, thanks again
<0> I believe there may be lot of other things also that bash inherited from other shells
<1> m4n, as usual, there are the good practise, and what should be used and what it is not :)
<0> groton: i have never seen &> is experimental or anything
<0> be it property of any shell, once being ported to bash, I think its fine to use them
<1> also windows is not experimental or anything, but using it is bad.
<0> who said using windows is bad
<0> its all personal interest
<1> me, who is actually using it :) anyway, i was kidding :P
<0> i dont have a windows box either.. but I dont think its bad using them .. everything has got its pros and cons
<2> koala_man: a/config sets a value ... a/b/config overrides it, but i want to the value from a/config again as default value for a/c/config
<3> Helo
<4> someone want to explain this to me:
<4> (4 line paste)
<4> [sunny@lexington ~]$ file foo
<4> foo: ASCII text
<4> [sunny@lexington ~]$ cat foo
<4> -bash: foo: command not found
<4> o_O
<5> you aliased "cat"?
<4> no
<5> what does "type cat" say?
<4> [sunny@lexington ~]$ ls -l foo
<4> -rw-rw-r-- 1 sunny sunny 30 Jun 12 23:20 foo
<4> cat is hashed
<5> what does it SAY?
<4> [sunny@lexington ~]$ type cat
<4> cat is hashed (/bin/cat)
<4> HAH! ... it does the same thing zsh
<5> hmm... what did you do to your system?
<5> did you corrupt /bin/cat?
<6> cat is hashed?
<6> cat is /bin/cat
<5> quag|work: "cat /dev/null; type cat"
<6> greycat: what do I do now?
<4> no, rpm -V reports /bin/cat being fine
<6> cat is hashed (/bin/cat)
<6> i don't like cat is hashed thing
<5> sunny: can you cat *other* files?
<5> quag|work: help hash; man bash
<6> greycat: i can
<5> quag|work: NOT YOU.
<4> greycat: cat works fine
<7> Is it possible to turn epoch time to some fancy format via date or any similar command?
<6> knt: nothing is impossible
<5> GNU date can do it. so can perl.
<5> gdate -d "1970-01-01 UTC + $SECONDS seconds"
<6> chmod -x /bin/chmod
<4> greycat: any ideas ?
<6> then you can still recover using perl
<5> sunny: hm... less? more? pg? vi?
<4> oh, wait
<4> file CONTAINS that line
<4> thats not cat outputting it
<4> hah
<5> hahahahahaha
<7> greycat: thanks, -d param solved my problem.
<4> [sunny@lexington ~]$ cat foo 1>/dev/null
<4> [sunny@lexington ~]$
<5> that's hilarious :)
<4> yeah
<4> it sure had me
<2> koala_man: You see the problem? Maybe i just stay with local, after all it's on ksh, bash and ash...
<2> The only thing i really miss in POSIX sh
<8> sup guys.. can someone recommend and good book for bash programing (or scripting depending on what u want to call it)?
<9> book ?
<8> ya
<9> have you already read through http://tldp.org/LDP/abs/html/
<9> ?
<9> :P
<10> and the other URLs in the topic..
<8> well.. i work for a non-profit org so printing a whole doc site is out of the question plus I prefer to read a book than on-screen
<8> hence, i am looking for a bok
<8> book*
<6> bash is not turing complete?
<6> i love bash
<11> i think bash is
<11> it has arrays, a pointer
<11> and it can move symbols
<11> it can even compare them
<12> /join #sed
<12> oops
<2> aixing: Shell Scripting Recipes: A Problem-Solution Approach
<8> kanaldrache: thnx
<2> aixing: It's my favourite
<8> :)
<13> If I read a file line by line with 'while read' and output the lines with echo. Can I somehow keep the whitespace in the lines? Right now the output lacks spaces/tabs.
<5> while IFS=$'\n' read -r line; do ...
<5> that will help preseve *leading* whitespace.
<5> if you're missing *internal* whitespace, it's not read's fault.
<5> !pitfalls
<14> http://wooledge.org/mywiki/BashPitfalls
<13> greycat: thank you :) Leading whitespace is all I need to preserve.
<15> how do i write in .bash_profile to tell it to keep a history file?
<5> it does that by default.
<5> or, "man bash, search for `hist'"
<16> sup all
<12> chalcedony: ping :)
<16> how could i use the output of ps ax|egrep "evolution --component=mail" to launch mail if its not running and not launch it if it is, problem is that it shows always one line: the egrep line itself
<17> is there any easy way to get the result of ps for only processes more than 10 minutes old?
<5> jesus.
<17> The hard way seems like parsing out the time from the ps output
<5> !faqrunning
<14> http://wooledge.org/mywiki/BashFaq#faq42 -- How can I find out if a process is still running?
<5> !faqmutual
<14> http://wooledge.org/mywiki/BashFaq#faq45 -- How can I ensure that only one instance of a script is running at a time (mutual exclusion)?
<18> I executed a while loop on my shell and now I can't get it to stop. ^C doesn't work. Am I forced to kill the process?
<5> !vagueness
<5> !learn vagueness VAGUENESS CAUSES HEART DISEASE!
<14> OK, greycat
<18> What my explanation to vague?
<19> if i have a variable $foo in a script and i want to 'wget something.com/$foo' how would i do that?
<20> greycat: on my web hosting env, it doesn't seem to generate bash history file
<5> WHAT doesn't?
<5> are you launching an interactive shell? are you running scripts from apache/CGI? from cron?
<21> Trying to write a script to remove empty files in a directory. It works, however I need to run it multiple times, so I think there is a problem with the while loop. http://pastebin.com/727511
<22> wtf
<22> find . -type f -size 0c -exec rm -f {} \;
<22> script?
<6> lol
<6> that's thedailywtf
<22> gertrude, wow
<21> Well thanks
<22> did you really write this to try and do that?
<21> yea
<22> man find
<22> find is your friend. its very powerful
<22> how would you gunzip several files at once and cat them all together
<10> gunzip *; cat * > foo?
<22> would that be faster than zcat *.gz > foo?
<10> or even gunzip -c * > foo?
<22> ah yep, didnt see that -c flag
<23> how to start two program in one command ?
<10> foo&bar
<18> prog1 && prog2
<18> or prog1; prog2
<18> of course, that is one line, not one command
<23> prog1 && prog2, cat work. I mean, the prog1 doesn't rethurn, and the prog2 starts
<18> right
<5> tell us what you want. you're not being clear.
<22> you cant do simultaneous command execution
<22> you can do sequential if you feel like
<5> you can do damned-close-to-simultaneous background jobs.
<22> nod
<5> but, he has to tell us what he *wants*.
<22> but close only counts in horseshoes and handgrenades
<23> I use sopcast : I want to start them at one terminal: prog1:sp-sc sop://211.152.34.35:3912/6002 10000 20000 and prog2:mplayer http://localhost:20000
<5> does one of them *use* the other in some way? they appear to be related.
<5> e.g., I would *guess* that mplayer is trying to read from the socket that the sp-sc program listens on.
<5> in which case, you need to start mplayer *after* sp-sc has already got the socket open and is ready.
Return to
#bash
or
Go to some related
