String handling

[ajayarora]

Hi,

I've a file with fields sperated by ~, like
1~2~3~4
1~x~y~z

My requirement is remove the first field and create another file rest of the fields like
2~3~4
x~y~z

I don't want to use "cut" command as it would be slow as compare to awk script. Any help would be appreciated.

Thanks.

I guess...
awk 'BEGIN {FS=OFS="~"}{print $2,$3,$4}' file1 > file2
or
awk '{print substr($0,index($0,"~&quot+1)}' file1 > file2

but both are slower than...
cut -d'~' -f2- file1 > file2

Try

awk '{sub("[^~]*~","");print}' infile > outfile

nawk -F'~' -v OFS='~' '{print substr($0,match($0,$2));}' file.txt

Thanks for your help. Don't we have something like -f2- in awk. Actually, the first field in the original file is a file-id and on the basis of which I've to create a file.
like
1~2~3~4 will result in a file say abc containing 2~3~4 and
2~x~y~z will go to another file say pqr containing x~y~z .

Try something like this:

awk -F'~' '
BEGIN{out[1]="abc";out[2]="pqr"} # and so on ..
{print substr($0,index($0,"~")+1)>out[$1]}
' /path/to/file

Hope This Help
