Hi!
1. I have a parameter file containing path to log files. For this example both paths are the same, one is stated directly and the second using env variables.
/oracle/admin/orcl/bdump/:atlas:trc:N
${ORACLE_BASE}/admin/${ORACLE_SID}/bdump/:${ORACLE_SID}:trc:N

Hi, my problem is that I have two files. File no. 1 is a gff text file (say gi1) that has gene information like :

Hi, all:
My writed network device driver works fine when the transmitted file is under several MegaBytes, but above this size, especially dozens of or hundreds of MegaBytes, the kernel panic ocurres! I check the kern.log and find this error :

Hey,
I've been trying to break a massive fasta formatted file into files containing each gene separately. Could anyone help me? I've tried to use the following code but i've recieved errors every time:
for i in *.rtf.out
do
awk '/^>/{f=++d".fasta"} {print > $i.out}' $i

Hi,
May i ask if someone share some command for extracting a string between 2 ref string in a txt file
My objective: i had a file with multiple lines and wants only to extract the string "watch?v=IbkAXOmEHpY" or "watch?v=<11 random character>", when i used "grep 'watch?=*' i got a results per... (4 Replies)
I am trying to modify the awk below to include the gene name ($5) for each target and can not seem to do so. Also, I'm not sure the calculation is right (average of all targets that are the same is $4 using the values in $7)? Thank you :).

io::seekable
IO::Seekable(3pm) Perl Programmers Reference Guide IO::Seekable(3pm)NAME
IO::Seekable - supply seek based methods for I/O objects
SYNOPSIS
use IO::Seekable;
package IO::Something;
@ISA = qw(IO::Seekable);
DESCRIPTION
"IO::Seekable" does not have a constructor of its own as it is intended to be inherited by other "IO::Handle" based objects. It provides
methods which allow seeking of the file descriptors.
$io->getpos
Returns an opaque value that represents the current position of the IO::File, or "undef" if this is not possible (eg an unseekable
stream such as a terminal, pipe or socket). If the fgetpos() function is available in your C library it is used to implements getpos,
else perl emulates getpos using C's ftell() function.
$io->setpos
Uses the value of a previous getpos call to return to a previously visited position. Returns "0 but true" on success, "undef" on
failure.
See perlfunc for complete descriptions of each of the following supported "IO::Seekable" methods, which are just front ends for the
corresponding built-in functions:
$io->seek ( POS, WHENCE )
Seek the IO::File to position POS, relative to WHENCE:
WHENCE=0 (SEEK_SET)
POS is absolute position. (Seek relative to the start of the file)
WHENCE=1 (SEEK_CUR)
POS is an offset from the current position. (Seek relative to current)
WHENCE=2 (SEEK_END)
POS is an offset from the end of the file. (Seek relative to end)
The SEEK_* constants can be imported from the "Fcntl" module if you don't wish to use the numbers 0 1 or 2 in your code.
Returns 1 upon success, 0 otherwise.
$io->sysseek( POS, WHENCE )
Similar to $io->seek, but sets the IO::File's position using the system call lseek(2) directly, so will confuse most perl IO operators
except sysread and syswrite (see perlfunc for full details)
Returns the new position, or "undef" on failure. A position of zero is returned as the string "0 but true"
$io->tell
Returns the IO::File's current position, or -1 on error.
