perf-mem - Profile memory accesses
SYNOPSIS
perf mem [<options>] (record [<command>] | report)
DESCRIPTION
"perf mem -t <TYPE> record" runs a command and gathers memory operation data from it, into perf.data. Perf record options are accepted and
are passed through.
"perf mem -t <TYPE> report" displays the result. It invokes perf report with the right set of options to display a memory access profile.
OPTIONS
<command>...
Any command you can specify in a shell.
-t, --type=
Select the memory operation type: load or store (default: load)
-D, --dump-raw-samples=
Dump the raw decoded samples on the screen in a format that is easy to parse with one sample per line.
-x, --field-separator
Specify the field separator used when dump raw samples (-D option). By default, The separator is the space character.
-C, --cpu-list
Restrict dump of raw samples to those provided via this option. Note that the same option can be passed in record mode. It will be
interpreted the same way as perf record.

tapset::perf - systemtap perf probe points
DESCRIPTION
This family of probe points is used to probe "perf events" on suitably configured kernels (2.6.33+). It contains a number of aliases for
the ABI-specified event type/config tuples.
The default sampling interval of the translator(1000000) is not overridden, so some of these probe points may fire very infrequently. Use
the lower level perf.type(AA).config(BB).sample(CC) probe point if this is a problem.
perf.hw.*
A variety of hardware events, as generalized by the kernel. These generally require running on bare hardware with selected proces-
sors.
probe perf.hw.cpu_cycles
probe perf.hw.instructions
probe perf.hw.cache_references
probe perf.hw.cache_misses
probe perf.hw.branch_instructions
probe perf.hw.branch_misses
probe perf.hw.bus_cycles
perf.sw.*
Special "software" events provided by the kernel. These sometimes work in virtualized environments and with more processor archi-
tectures.
probe perf.sw.cpu_clock
probe perf.sw.task_clock
probe perf.sw.page_faults
probe perf.sw.context_switches
probe perf.sw.cpu_migrations
probe perf.sw.page_faults_min
probe perf.sw.page_faults_maj
probe perf.sw.alignment_faults
probe perf.sw.emulation_faults
perf.hw_cache.TYPE.ACCESS.RESULT
Hardware cache events, where available. A subset of the following cartesian product may be available:
probe perf.hw_cache.l1d.*.*
probe perf.hw_cache.l1i.*.*
probe perf.hw_cache.ll.*.*
probe perf.hw_cache.dtlb.*.*
probe perf.hw_cache.itlb.*.*
probe perf.hw_cache.bpu.*.*
probe perf.hw_cache.*.read.*
probe perf.hw_cache.*.write.*
probe perf.hw_cache.*.prefetch.*
probe perf.hw_cache.*.*.access
probe perf.hw_cache.*.*.miss

Hi guys!
I need to cut first row from a file (using awk) without the record separator character (in my case its MS-DOS 0D0A) and field separator character (in my case ; 3B) and put it in another file.
Can you help with that?
