Hi
I'm trying to read the output of 'ls -lartF' into an array, a line
into each array element
I've tried to do this in 3 different ways
1. I've managed to do this is using a two way pipe, as follows:
#!/bin/ksh
i=0
ls -lartF |&
while read -p line; do
print - "$line"
aline[i]="$line"
let i=i+1
done
Is there a way of doing the this without being a smartass (i.e.
without two way pipes)
2. In the following way it's all read as a single line into the first
array element:
#!/bin/ksh
i=0
print -r $(ls -lartF) > tmpshiron
while read -r line; do
print -r "$line"
aline[i]="$line"
let i=i+1
done < tmpfile
rm tmpfile
how can I read the output as lines?
is there a way I can read the lines without using a tempfile ???
3. I've tried (and failed) "feeding" the loop from the subprocess, as
follows:
while read -r line; do
..
..
done < $(ls -lartF)
what is the most straight forward way of doing this?
Simple pipes...
ls -lartF |
while read -r line; do
...
done
Or, if you want to work on separate fields within the loop, enumerate
the fields in the read list...
ls -lartF |
while read -r var1 var2 var3 rest_of_line
do
...
done

Thanks
