Copies only such numbers of input blocks
Access the input file with
use direct I/O for data
fail unless a directory
use synchronized I/O for data
pad every input block with NULs to ibs-size
accumulate full blocks of input
use non-blocking I/O
do not update access time
do not assign controlling terminal from file
do not follow symlinks
Write the output file with
append mode (conv=notrunc suggested)
use direct I/O for data
fail unless a directory
use synchronized I/O for data
use non-blocking I/O
do not update access time
do not assign controlling terminal from file
do not follow symlinks
Skips such numbers of blocks from beginning of output file before copying
Skips such numbers of input blocks before starting to copy
Suppress transfer statistics
Converts input data
Converts records length

Converts characters
from EBCDIC to ASCII
from ASCII to EBCDIC
from ASCII to alternate EBCDIC
Converts records length
pad newline-terminated records with spaces to "converts block size"
replace trailing spaces in "converts block size" records with newline
Converts case sensive characters
change upper case to lower case
change lower case to upper case
Converts output file options
do not create the output file
fail if the output file already exists
Do not truncate the output file
Physically write output file data before finishing
Physically write output file data and metadata before finishing
Other converts options
Continue after read errors
Use synchronized I/O for data and metadata
