Answer 1

使用一个小awk脚本：

 awk -F: '{printf "http://mysever.com/2/tasks.php?account=%s%%3A%s\n", $1, $2}' < my.txt > my2

Answer 2

Very basic on bash:

while IFS=":" read u p
do
  echo "http://mysever.com/2/tasks.php?account=$u%3A$p"
done < my.txt > my2.txt

Test

$ while IFS=":" read u p; do echo "http://mysever.com/2/tasks.php?account=$u%3A$p"; done < file > my2.txt
$ cat my2.txt
http://mysever.com/2/tasks.php?account=user%3Apass
http://mysever.com/2/tasks.php?account=user%3Apass
http://mysever.com/2/tasks.php?account=user%3Apass
http://mysever.com/2/tasks.php?account=user%3Apass

Answer 3

Using sed : You can use -i option to do infile substitutions or redirect to a new file

$ sed 's,\(.*\):\(.*\),http://mysever.com/2/tasks.php?account=\1%3A\2,' my.txt > my2.txt
http://mysever.com/2/tasks.php?account=user%3Apass
http://mysever.com/2/tasks.php?account=user%3Apass
http://mysever.com/2/tasks.php?account=user%3Apass
http://mysever.com/2/tasks.php?account=user%3Apass

Using awk :

$ awk -F: '{print "http://mysever.com/2/tasks.php?account="$1"%3A"$2}' my.txt > my2.txt
http://mysever.com/2/tasks.php?account=user%3Apass
http://mysever.com/2/tasks.php?account=user%3Apass
http://mysever.com/2/tasks.php?account=user%3Apass
http://mysever.com/2/tasks.php?account=user%3Apass

Answer 4

Perl solution:

perl -ne 'chomp; ($user, $pass) = split /:/;
  print "http://mysever.com/2/tasks.php?account=$user%3A$pass\n"' my.txt

Answer 5

Does what you want and discards lines with empty fields (eg, empty lines):

while read l; do
    [[ $l =~ .+:.+ ]] || continue
    printf "http://mysever.com/2/tasks.php?account=%s\n" "${l/:/%3A}"
done < my.txt > my2.txt
