While IF question
Hei everyone,
I have a text file usrccnr.txt like so: 53 fefwgergre 33 grgergrgeer 31 gregregrgeg 13 greregregreghkuy 13 kjkjkgkjg 12 mhlkkgfpdhj 12 mlglfjdkz 12 jgfjdahu 12 ngrkeow 12 nfrkeoqeirw 11 mfklewqjeo 11 mkfdlajfkrl 11 klrepkgowperw 11 coawerw 11 ferfjrqwh 10 erwqjfioreq 10 fkreqwjreq 8 gkrelwpgjkreo 7 jireojwfirojgre 6 korepwkpgre 4 kgropqejgorqe 4 gramk 4 rgek 3 ned 3 grogpekrwe 2 vlvrew 2 vasrer 2 spsi 2 resi 2 gregregw 2 frekroekgoe 2 grelkre 2 mafm 2 grearge 2 gregrga 2 lerkwofkrso 2 grod 2 mlkremwkrg 2 mrkemwegrihw 2 mkrejwgmrweogrew 2 grlewmgrewmg 2 rlewmgleg 2 antgrewgwe 2 anagirgerse 2 agrekor 1 trwegtmkr 1 gregrew 1 greewrge 1 zourgrew 1 zonkergeqzs 1 gremrkea What I am trying to do is create 2 seperate files containing: all text with the number 4 and higher to go to one file and the rest to another one. This is the code I came up with but NO, it does not work: while read $cnr $usr do if ($cnr>3) then printf "%s \n" $usr >> mc.txt else printf "%s \n" $usr >> lc.txt; fi done < usrccnr.txt; Could you please help? |
cat usrccr.txt | while read a b
do if [ $a -gt 3 ] then echo "$a $b" >> mc.txt else echo "$a $b" >> lc.txt fi done |
I should have read more! Thnx. It's been too many hours. SOLVED

Please use [code][/code] tags around your code and data, to preserve formatting and to improve readability. Please do not use quote tags, colors, or other fancy formatting.
Processing of field-based input can usually be handled more efficiently with awk. Code:
awk '{ if ( $1 > 3 ) { print $2 > "mc.txt" } else { print $2 > "lc.txt" } }' usrccnr.txt http://www.grymoire.com/Unix/Awk.html http://www.gnu.org/software/gawk/man...ode/index.html http://www.pement.org/awk/awk1line.txt http://www.catonmat.net/blog/awk-one...ined-part-one/ As for your original code, you got the basic idea right. But there are some syntax errors (you don't use "$" when setting variables, for example), and you need to use a proper set of arithmetic evaluation brackets for the test. Code:
while read cnr usr ; do http://mywiki.wooledge.org/Arguments http://mywiki.wooledge.org/WordSplitting http://mywiki.wooledge.org/Quotes I also recommend taking the time to more cleanly format your code, as I did above. |
