Thank you,
$count variables calculates the length of the line and if its length is fewer than 500 it writes to NEWFILE or to REJFILE. How can I write this
Hi all,
I have a flat file of 1000 rows. I want to check the length of the 5th column. The one having the longest length , I want to set it as DEFINED PARAMETER.
So later I can check others with that particular number only.
Any ideas ?? (2 Replies)
Hi All,
Please advise . Welcome more suggestions.
For examples, I have 1000 file with prefix x??? In fact, I want to convert them to x???.txt with max 10 files at a time. As such, I will need to call another script to read from those 10 *txt files and sleep 5000 to convert the next 10 again.... (10 Replies)

TM(4) Kernel Interfaces Manual TM(4)NAME
tm - TM-11/TU-10 magtape interface
DESCRIPTION
The files mt0, ..., mt7 refer to the DEC TU10/TM11 magtape. When closed it can be rewound or not, see below. If it was open for writing,
two end-of-files are written. If the tape is not to be rewound it is positioned with the head between the two tapemarks.
If the 0200 bit is on in the minor device number the tape is not rewound when closed.
A standard tape consists of a series of 512 byte records terminated by an end-of-file. To the extent possible, the system makes it possi-
ble, if inefficient, to treat the tape like any other file. Seeks have their usual meaning and it is possible to read or write a byte at a
time. Writing in very small units is inadvisable, however, because it tends to create monstrous record gaps.
The mt files discussed above are useful when it is desired to access the tape in a way compatible with ordinary files. When foreign tapes
are to be dealt with, and especially when long records are to be read or written, the `raw' interface is appropriate. The associated files
are named rmt0, ..., rmt7. Each read or write call reads or writes the next record on the tape. In the write case the record has the same
length as the buffer given. During a read, the record size is passed back as the number of bytes read, provided it is no greater than the
buffer size; if the record is long, an error is indicated. In raw tape I/O, the buffer must begin on a word boundary and the count must be
even. Seeks are ignored. A zero byte count is returned when a tape mark is read, but another read will fetch the first record of the new
tape file.
FILES
/dev/mt?, /dev/rmt?
SEE ALSO tp(1)BUGS
If any non-data error is encountered, it refuses to do anything more until closed. In raw I/O, there should be a way to perform forward
and backward record and file spacing and to write an EOF mark.
