Extracting a string matching a pattern from a line
Hi All,

I am pretty new to pattern matching and extraction using shell scripting. Could anyone please help me in extracting the word matching a pattern from a line in bash.

Input Sample (can vary between any of the 3 samples below):
1) Adaptec SCSI RAID 5445
2) Adaptec SCSI 5445S RAID
3) ICP ICP5085BL SATA RAID

Expected Output:
1) 5445
2) 5445S
3) ICP5085BL

I tried various options and zero'ed in with the below sed
Code:
echo "$1" | sed 's/.*\([0-9]\{4\}.*\)/\1/'


Though the above script works for the first 2 inputs it does not work for the third option. It gives only 5085BL instead of ICP5085BL. Any suggestions would be deeply appreciated.

AIC(4)                                                   BSD/i386 Kernel Interfaces Manual                                                  AIC(4)

NAME

     aic -- Adaptec AIC-6260 and AIC-6360 SCSI driver

SYNOPSIS

     device aic

     In /boot/device.hints:
     hint.aic.0.at="isa"

DESCRIPTION

     The aic driver provides support for the Adaptec AIC-6260 and AIC-6360 SCSI controller chips.  Many systems that use these controller chips do
     not have a boot ROM and therefore cannot be booted from.

HARDWARE

     The adapters supported by the aic driver include:

     o   Adaptec AHA-1505 (ISA)
     o   Adaptec AHA-1510A, AHA-1510B (ISA)
     o   Adaptec AHA-1520A, AHA-1520B (ISA)
     o   Adaptec AHA-1522A, AHA-1522B (ISA)
     o   Adaptec AHA-1535 (ISA)
     o   Creative Labs SoundBlaster SCSI host adapter (ISA)
     o   Adaptec AHA-1460, AHA-1460B, AHA-1460C, AHA-1460D (PC Card)
     o   Adaptec AHA-1030B, AHA-1030P (PC98)
     o   NEC PC-9801-100 (PC98)

SEE ALSO

BUGS

     The driver does not work well with multiple devices on the SCSI bus.  The driver works well with devices like CDROMs and Tape drives.  The
     driver works not so well with disk drives.  The PC Card version appears to work better than the ISA version, but that may be due to differing
     levels of testing of the devices.
