<0> I'm calling GNU sed with `sed -i -r -s -f foo.sed [123].txt'. One of the commands in foo.sed only needs to be applied to 2.txt; is there a way to care about filenames within foo.sed?
<1> Doubt it.
<0> Yeah. I'll implement some magic in the parent script.
<1> probably better to use a shell script
<1> Aye.
<0> Is -rsi equilvalent to -i -r -s?
<0> I know the -i has to be last.
<1> rsi is repetative strain injury !
<0> repetetive
<1> heh
<1> :-)
<1> Should be, try it.
<0> I got confused a moment ago because -ie worked but -if didn't :-)
<0> The expression /foo/d deletes lines matching foo. How can I delete each line that matches foo, plus the following two lines?
<0> Ah, /foo/,+2d
<2> when there is a matching expression for this line I get an empty page..(cat install/conf.sim | sed "/START-$STR_SERVICE_UPPER/,/END-$STR_SERVICE_UPPER/d" > install/conf.sim) , but when I redirect to foo.tmp I get the result I want(cat install/conf.sim | sed "/START-$STR_SERVICE_UPPER/,/END-$STR_SERVICE_UPPER/d" > foo.tmp) also when it doesn't match it works as well.. Is there some buffer flag I'm missing or is this obvious you can't read and edit the page
<1> codestr0m: you need to use a temp file, or if you have GNU sed, sed -i
<1> also, don't use cat file | sed
<1> sed 'sed;commands' file
<2> goldfish: ty.. I ended up using a temp file and trying to make this as universal as possible.. *bsd doesn't usually have GNU sed does it?
<1> no
<1> temp file is the portable solution
<1> sed 'blah' file > TMP_FILE && mv TMP_FILE file
<1> you'll see that alot
<2> goldfish: does move or copy make a difference.. like move is just swapping inodes or something?
<2> ooh if you move you don't have to delete the tmp file afterwards
<1> Indeed.
<2> I was going to play with something like this.. find install/* -type f -name "*" | xargs cat | sed '/STARTss/,/ENDss/d' >
<1> mv will not, change a file's inode
<1> k
<1> http://wooledge.org/mywiki/BashFaq#faq8 -- How can I recursively search all files for a string?
<2> any quick fixes on that line so I'm not pulling each file individually and thanks
<1> Should be a good read for you, it's only small.
<2> (oopse this is probably a case of missing something obvious. ) thanks
<3> hi
<3> how can i simply print out lines that match a given regexp from standar input?
<2> there is an example for the regex part http://www.student.northpark.edu/pemente/sed/sed1line.txt and "$FOO" will work, but '$FOO' won't
<1> Demian: sed -n '/regexp/p'
<1> codestr0m: anything inside single quotes is taken literally, no interpolation occourse.
<1> *occours
<2> goldfish: he said he wanted to pull a variable from stdin.. (sed "/START-$STR_SERVICE_UPPER/,/END-$STR_SERVICE_UPPER/d" install/sim )
<1> oh
<1> did he?
<1> Hmmmmm.
<4> hi I had to use sed on maxosx yeasterday, and I checked that the -i option was in that version of sed, because I had to edit the files. however, if I did "sed -i 's/foo/bar' *.dat" but if I did "sed -i -e 's/foo/bar' *.dat" it did what I expected except I got a copy of all .dat files which was named .dat-e ; Can anybody tell me what point i missed?
<5> It seems you missed the man page which describes how to use the -i option.
<5> Don't fret; not reading the manual may be a common mistake, but it is easily fixed. :)
<4> I am not on macosx now, so I can't check it, but would it differ from GNU/sed I tested it in linux with a GNU sed, where it worked
<5> I don't know, would it?
<4> well it did not change anything to read the man yeasterday!
<5> It seems that the -i option on GNU sed is slightly different than the -i option on BSD sed.
<4> hmm
<4> okay
<4> thank you
<4> so the difference in -i made me get the -e on all files
<4> I will read the BSD man page next time I get near such a Mac beast ;)
<5> mine says: ''-i _extension_''
<5> My GNU man page says ''-i_suffix_''
<4> okay
