yes, because it builds a string and it has no need for eval LST="" for index in 1 2 3 do LST=$LST" "$index done echo "LST= " $LST should result in: LST= 1 2 3 the next trick is to use set -- $LST now you can access via $1 $2 $3 ... if that is a good idea depend on the program itself. re, wh > > On Fri, Jun 26, 2015 at 3:27 PM, walter harms <[email protected]> wrote: > >> [image: Boxbe] <https://www.boxbe.com/overview> [email protected] is not on your >> Guest List >> <https://www.boxbe.com/approved-list?tc_serial=21777443206&tc_rand=652426986&utm_source=stf&utm_medium=email&utm_campaign=ANNO_MWTP&utm_content=001&token=aDeOtixSIEH3%2F0Ze0cAv3ydDN957%2BNU3ojgLwj2ek%2F4gXUWcTJ0iLwUhbD5cG%2B2F&key=f6wuCr76tTrCLRy6zk1fMqykcfj899VyTLRSWEJBniU%3D> >> | Approve sender >> <https://www.boxbe.com/anno?tc_serial=21777443206&tc_rand=652426986&utm_source=stf&utm_medium=email&utm_campaign=ANNO_MWTP&utm_content=001&token=aDeOtixSIEH3%2F0Ze0cAv3ydDN957%2BNU3ojgLwj2ek%2F4gXUWcTJ0iLwUhbD5cG%2B2F&key=f6wuCr76tTrCLRy6zk1fMqykcfj899VyTLRSWEJBniU%3D> >> | Approve domain >> <https://www.boxbe.com/anno?tc_serial=21777443206&tc_rand=652426986&utm_source=stf&utm_medium=email&utm_campaign=ANNO_MWTP&utm_content=001&dom&token=aDeOtixSIEH3%2F0Ze0cAv3ydDN957%2BNU3ojgLwj2ek%2F4gXUWcTJ0iLwUhbD5cG%2B2F&key=f6wuCr76tTrCLRy6zk1fMqykcfj899VyTLRSWEJBniU%3D> >> >> >> >> Am 26.06.2015 11:07, schrieb Pratik Prajapati: >>> Thanks.
