Error Truncate all characters and numbers in string - using perl
hi,

I have an data from file where it has
Code:
20110904 234516  <<hdd-10#console|0c.57,passed,5,28,READ,0,20822392,8,5,4,0,40,0,-1,0,29909,25000,835,3.3,0,0,0,0,implied,0,0,2011/9/5-2:3:17,2011/9/5-2:3:47,X292_0F15,TAP  ,NQ09,J40LTG\r\r\n

I want to remove characters till #console| i.e want to remove
Code:
20110904 234516  <<hdd-10#console|

So that result must be
Code:
0c.57,passed,5,28,READ,0,20822392,8,5,4,0,40,0,-1,0,29909,25000,835,3.3,0,0,0,0,implied,0,0,2011/9/5-2:3:17,2011/9/5-2:3:47,X292_0F15,TAP   ,NQ09,J40LTG

it must truncate last characters \r\r\n also.
