<0> I don't see how you can get that error from sed unless one of the variables being expanded contains either a slash or a newline.
<0> or possibly a trailing backslash
<1> Just in case I ***igned LOCVAR like this
<1> TMPVAR="`grep somealias /tmp/aliases`,$loginname"
<0> so it contains multiple lines, separated by newlines.
<0> that would do it.
<1> greycat, Well... somealias is a huge alias...
<0> also, WHY are you putting the output of grep into that variable? All you wanted to add was the ,$loginname part, right?
<1> well.. Actually.. We have many aliases... say around 100
<1> diff department when a new user joins..
<1> We will update alias based on his dept
<0> And somehow they ***igned *you* this job, despite your utter inability to manage simple unix commands...?
<0> now, run this: echo "$LOCVAR"
<1> so The idea was to search for somealias and append his email./loginname
<0> And paste the result here.
<0> And then run this: echo "$TMPVAR"
<0> And paste the result here.
<0> Do NOT omit the quotation marks.
<0> KEEP the quotation marks.
<1> echo $LOCVAR
<0> WRONG.
<1> somealias
<0> WRONG WRONG WRONG.
<1> echo "$LOCVAR"
<1> somealias
<0> you are lying, aren't you?
<2> i have two trees - /proj/prod and /proj/test. under each tree we have directories like "cgi" which we access using $CGI. is there some way to set BASE=/proj/prod and CGI=$BASE/cgi, such that when base gets changed so does CGI, or do you have to re-set all those relative paths?
<0> just change both variables.
<0> seriously. it's one extra line.
<1> greycat, Well.. Lying in one thing.. somealias is a diff a legitimate email id
<1> greycat, well.. Something interesting here...
<0> if you set LOCVAR=somealias TMPVAR=,someloginname does it WORK THEN?
<1> if I do echo "$TMPVAR"
<0> ... you get multiple lines, right?
<1> Yup

<0> #10.
<0> !quotes
<3> USE MORE QUOTES! http://www.grymoire.com/Unix/Quote.html
<1> greycat, Now I got it working... But
<1> Now I can see two somealias than one
<0> Here we go again....
<1> one original and the otherone with the new entry appended to it
<0> Because you have the wrong thing in your TMPVAR.
<0> You have that godawful thing where you grepped a WHOLE LINE and then added stuff on to the end of it, instead of just having the part you want to add.
<1> Now I modified it to TMPVAR="`grep ^localblrori /tmp/aliases`,$loginname"
<0> TMPVAR should just contain ',foo'
<1> and echo "$TMPVAR" shows one line
<0> TMPVAR=",$loginname"
<0> It should NOT have the whole line.
<1> grepper, oops .. Got it
<4> would like to read up on ${foo:0:8} where can i find docs on this?
<1> one sec
<5> is there a way to get echo to show my all the excape chars it's interping? something looks fishy about my output
<0> !pe
<3> Parameter Expansion. Expressions like ${foo%.mp3} and so on -- see man bash, and then search for Parameter Expansion. See also, http://wooledge.org/mywiki/BashFaq#faq74 and http://tiswww.tis.case.edu/~chet/bash/bashref.html#SEC30.
<5> *escape
<0> fedx_: remove the -e and it won't interpret anything.
<4> parameter expansions. cool. did not know what it was called. thanks
<5> it's doing this wierd thing where i tell it echo "$afile.txt" and it echos .txt<filename>
<1> greycat, Man.. You are a genius
<0> sounds like you have a literal carriage return inside afile
<0> did you get it by grepping something from a file that's been edited by a Windows luser?
<5> that's what i figured
<1> greycat, It works like a dream
<5> do it
<5> ack.. no it's mysql output
<0> echo "$afile" | cat -e
<0> another handy one is od -t x1 <<< "$afile" but remember that this adds a newline just like echo.
<0> and unlike echo, there's no -n to avoid that.
<5> er no i don't want it to cat my file
<0> *headdesk*
<5> the mysql output is a list of files and i want to store <afilename>.txt in a var
<5> nevermind.
<5> got ya
<5> it's a ^M,.. which is that?
<0> that's a carriage return.
<6> greycat : whats the opposite of od?
<7> thats dos nonsense
<0> Staz: what are you trying to do?
<6> Just curious how to reverse the 'od' process.
<0> you don't, usually.
<8> I need to concatenate parameters in a while until loop ... so ... how $mynewvar should be? mynewvar=$mynewvar + ${$counter} ? anyone can help with that ?
<0> !faq concat
<3> http://wooledge.org/mywiki/BashFaq#faq13 -- How can I concatenate two variables?
<8> the problem its with $1 $2 variable
<0> I see a lot of problems, and the first was the phrase "while until loop".
<8> that index need to be another variable
<0> !faq variable variable
<3> http://wooledge.org/mywiki/BashFaq#faq44 -- How can I use ***ociative arrays or variable variables?
<8> hehe, its the same problem with both cmds ... thats not the problem, its with $1 parameters
<0> nwe: speak English, damn it.
<8> well, ok, the problem its with parameter variable, not with flow control syntaxis
<0> !faq variable variable
<3> http://wooledge.org/mywiki/BashFaq#faq44 -- How can I use ***ociative arrays or variable variables?
<0> That?
<8> im checking thnx
<8> STRING_OUT="$STRING_OUT + '$'$COUNTER";
<8> i need todo that in a loop
<8> to store function parameters in STRING_OUT
<0> PARAMETERS=(foo bar baz)
<0> i=3

<0> !faq dialog
<3> http://wooledge.org/mywiki/BashFaq#faq40 -- How do I use dialog to get input from the user?
<0> There's a really good example in there.
<9> quick question how can I program in like a 'break' where the bash script will wait for the user to press enter to continue?
<10> read
<8> thanks grey there are lots of examples there i think i could use
<11> hi
<0> !faq pause
<3> http://wooledge.org/mywiki/BashFaq#faq65 -- Is there a "PAUSE" command in bash like there is in MSDOS batch scripts? To prompt the user to press any key to continue?
<0> !learn users http://wooledge.org/mywiki/BashFaq -- Why don't users ever read the FAQ themselves? Why do I always have to grep the whole file for their questions? Huh? Doesn't anyone ever think of the bot?
<3> OK, greycat
<12> http://www.pastebin.ca/345711
<12> what is wrong in that script ?
<13> you're the one who has run it - how does its behaviour differ from what you want?
<14> Asche: nothing
<12> but when i run it
<12> void:/# ./prueba
<12> ./prueba: line 12: syntax error: unexpected end of file
<12> void:/#
<15> there is a ';' missing before the '}' on line 5
<15> additionally the script cannot handle file names with whitespace, and is badly formatted
<6> pastebin still hasn't loaded for me :P
<13> Staz: no huge loss
<12> it stills
<12> ./prueba: line 12: syntax error: unexpected end of file
<15> Asche: could you post your corrected version?
<6> to rafb this time :P
<12> yes
<0> !pastebins

<0> !forget pastebins
<3> OK, greycat
<0> !learn pastebins http://rafb.net/paste - http://pastebin.ca
<3> OK, greycat
<7> rafb is good
<12> today i started with bash
<12> hehe
