Perl RegExp to remove last character from strings

I use SAS (a statistical software) and have to remove last character or the last 1/2 numbers that appear after characters from the string using Perl Regular Expression (which is recognized by SAS).

Input: f183ii10 f183ii2 f182ii1 f182ii2 f183iim f22ii f22ii11 f22ii12 pmh4 pmhm

Desired Output:f183ii f183ii f182ii1 f182ii2 f183ii f22ii f22ii f22ii pmh pmh

smp_rep_phy_event_list - invoke REPORT PHY EVENT LIST SMP function SYNOPSIS
smp_rep_phy_event_list [--help] [--hex] [--index=IN] [--interface=PARAMS] [--raw] [--sa=SAS_ADDR] [--verbose] [--version] [--zero] SMP_DEVICE[,N] DESCRIPTION
Sends a SAS Management Protocol (SMP) REPORT PHY EVENT LIST function request to a SMP target. The SMP target is identified by the SMP_DEVICE and the SAS_ADDR. Depending on the interface, the SAS_ADDR may be deduced from the SMP_DEVICE. The mpt interface uses SMP_DEVICE to identify a HBA (an SMP initiator) and needs the additional ,N to differentiate between HBAs if there are multiple present. OPTIONS
Mandatory arguments to long options are mandatory for short options as well. -h, --help output the usage message then exit. -H, --hex output the response (less the CRC field) in hexadecimal. -i, --index=IN starting phy event list descriptor index. ID is a value between 1 and 65535. Default is 1. -I, --interface=PARAMS interface specific parameters. In this case "interface" refers to the path through the operating system to the SMP initiator. See the smp_utils man page for more information. -r, --raw send the response (less the CRC field) to stdout in binary. All error messages are sent to stderr. -s, --sa=SAS_ADDR specifies the SAS address of the SMP target device. Typically this is an expander. This option may not be needed if the SMP_DEVICE has the target's SAS address within it. The SAS_ADDR is in decimal but most SAS addresses are shown in hexadecimal. To give a number in hexadecimal either prefix it with '0x' or put a trailing 'h' on it. -v, --verbose increase the verbosity of the output. Can be used multiple times -V, --version print the version string and then exit. NOTES
Similar information is maintained for SAS SSP target phys (e.g. on a SAS disk). It can be obtained from the Protocol Specific Port log page with the sg_logs utility. Similar information may be obtained for SAS initiator phys (e.g. on a SAS HBA). As an example in Linux 2.6.28 error information can be found in this directory /sys/class/sas_phy/phy-4:0 (for the phy 0 in SCSI/SAS host 4). Similar information may be obtained for SATA device phys (e.g. on a SATA disk). If there is a SAT layer between OS and the SATA device then the sg_sat_phy_event utility can fetch the information.

The SMP REPORT PHY EVENT LIST function was introduced in SAS-2 . AUTHORS
