Full Discussion: Array copy in ksh

If we remove all """ and indenting for readability we are left with:

Code:
fileLimit=5
func ()
{
 dir="$1"
 format="$2"
 array="$3"
 i=0
 ls -lrt $format | tail -${fileLimit} | while read f_det
do
      files[i]="${f_det}",
      ((i+=1))
done
eval $(echo set -A $array '${files[@]}')
}
 
func . "*.pl" a
echo ${a[@]}

Bearing in mind that I never use arrays and cannot verify that code. There is probably a spurious comma, but the main problem is that we are expanding "*.pl" on the function call rather than within the function. Needs quotes until the point when you actually want to expand the "*". Better to quote every text variable as good practice. There is also a space character missing on the function header (which might still work in some shells).

Because "ls -l" gives more than one field and more than one line (with tail -5) the best I can suggest is to put quotes round ${f_det}. I really don't know whether this will end up in the array. ... others will.



Btw. If you have further issues, please post what you typed, what you expected to happen, and what actually happened (including any error messages).

Ksh array solution.

I was wondering if ksh supported arrays. I have a script that may work with several hosts. I'd like a means of knowing how many hosts I'm working with and an easy way to access them (as variables) in a loop. I'm assuming there's some kind of foreach in shell scripting. (1 Reply)
