shell while loop broken after using AWK

[byh]

#!/bin/sh

while read x1 x2 x3 x4 x5 x6 x7 x8 nc
do

eval "$(awk -v string="$nc" 'BEGIN {num=split(string,a,"/")} {len=length(string)} {lenx=length(a[num])} {printf "cdir=%s\n", substr(string,1,len-lenx-1)} END {printf "fnm=%s\n", a[num]}' )"

echo 'nc='$nc' cdir='$cdir' fnm='$fnm
done < /ptmp/wx52bh/fileMir.loc

Since the text in file fileMir.loc is more than one line, I expect to have more than one output.
However, the program stops after one output.

Any solutions or problems?

Thanks

Your awk program read its standard input, ie fileMir.loc !
you may try this instead:
eval "$(awk -v string='$nc' 'BEGIN{num=split(string,a,"/");len=length(string);lenx=length(a[num]);printf "cdir=%s\nfnm=%s\n", substr(string,1,len-lenx-1), a[num]}')"

Hope This Helps, PH.

Dear PH,

Thanks to your reply, the program works much better. The loop continues as I wanted. But the out puts are not quite right:

The line read is "/u/wx52bh/tmp/grads/get_time.gsf"

I wish to get two line outputs
cdir=/u/wx52bh/tmp/grads
fnm =get_time.gsf

But what I got is
cdir=
fnm =/u/wx52bh/tmp/grads/get_time.gsf

Which is very strange.
Any further advice is expected and will be very much appreciated.

In fact you don't need awk at all:
while read x1 x2 x3 x4 x5 x6 x7 x8 nc
do
cdir=$(dirname "$nc")
fnm=$(basename "$nc")
echo 'nc='$nc' cdir='$cdir' fnm='$fnm
done < /ptmp/wx52bh/fileMir.loc

Hope This Helps, PH.
