In reply to @vbits:matrix.org
I would like to do a script that test a urls list .txt and give a output the effective url (302)

I found this one:
#!/bin/bash
curl $1 -s -L -I -o /dev/null -w '%{url_effective}'

but it just for one link that I have to write.. someone can help me please?

#!/bin/bash

# usage:
# check-urls [path/to/list.txt] [path/to/result.txt]

LISTFILE=${1:-'list.txt'}
RESFILE=${2:-'res.txt'}

URLS=$(cat $LISTFILE)

for U in $URLS; do
    EU=$(curl $U -s -L -I -o /dev/null -w '%{url_effective} (%{http_code})')
    echo "$U >> $EU" >> "$RESFILE"
done

Something like that?
