十进制和十六进制间的转换
为了在十进制和十六进制之间转换较大的数值，最好是让计算机来完成这项工作。例如，下面的perl语言脚本将一列数字从十进制转换为十六进制：
#!/usr/bin/perl
# Convert list of decimal numbers into hex for ($i = 0; $i < @ARGV; $i++)
{
printf ("%d = 0x%x\n",$ARGV[$i], $ARGV[$i]);
}
[zhanghua@localhost data]$ chmod +x d2h [zhanghua@localhost data]$ ./d2h 100 500 82
100 = 0x64
500 = 0x1f4
82 = 0x52
下面的脚本将十六进制转换为十进制： #!/usr/bin/perl
# Convert list of hex numbers into decimal for ($i = 0; $i < @ARGV; $i++)
{
$val = hex($ARGV[$i]);
printf ("0x%x = %d\n",$val, $val);
}
[zhanghua@localhost data]$ chmod +x h2d
[zhanghua@localhost data]$ ./h2d 64 1f4 52
0x64 = 100
0x1f4 = 500
0x52 = 82
# Convert list of decimal numbers into hex for ($i = 0; $i < @ARGV; $i++)
{
printf ("%d = 0x%x\n",$ARGV[$i], $ARGV[$i]);
}
[zhanghua@localhost data]$ chmod +x d2h [zhanghua@localhost data]$ ./d2h 100 500 82
100 = 0x64
500 = 0x1f4
82 = 0x52
下面的脚本将十六进制转换为十进制： #!/usr/bin/perl
# Convert list of hex numbers into decimal for ($i = 0; $i < @ARGV; $i++)
{
$val = hex($ARGV[$i]);
printf ("0x%x = %d\n",$val, $val);
}
[zhanghua@localhost data]$ chmod +x h2d
[zhanghua@localhost data]$ ./h2d 64 1f4 52
0x64 = 100
0x1f4 = 500
0x52 = 82
