Hello,
I am working on unix for the first time.
I have to write a shell script where i want to cut paste from one file to other.
File "1234.abc" is
Here in "03,12345555", 03 indicates line id and 12345555 indicates account number of user. The subsiquent lines are details for account number 12345555 till record "49,12345555"
From next line, details for new account number eg.12347710 starts
My requirement is if i give parameter as 12347710, all records for this accounts should be cut from File "1234.abc" and should be pasted in new file "1234.7710" (ie name of original file and extn is last four digits of parameter)
so new "1234.abc" will be
and "1234.7710" will be

trace-cmd-mem
TRACE-CMD-MEM(1)TRACE-CMD-MEM(1)NAME
trace-cmd-mem - show memory usage of certain kmem events
SYNOPSIS
trace-cmd mem [OPTIONS][input-file]
DESCRIPTION
The trace-cmd(1) mem requires a trace-cmd record that enabled the following events:
kmalloc
kmalloc_node
kfree
kmem_cache_alloc
kmem_cache_alloc_node
kmem_cache_alloc_free
It then reads the amount requested and the ammount freed as well as the functions that called the allocation. It then reports the final
amount of bytes requested and allocated, along with the total amount allocated and requested, as well as the max allocation and requested
during the run. It reports the amount of wasted bytes (allocated - requested) that was not freed, as well as the max wasted amount during
the run. The list is sorted by descending order of wasted bytes after the run.
