Hi,
I am new to this forum and new to awk.
I have a file that contains 2 columns.
Heres an example of what it looks like:
10 +
20 +
40 +
50 -
70 -
So the file is tab-delimited. What I want to do is add 10 to column 1 whenever column 2 is + and substract 10 from column 1... (1 Reply)

Hi,
I have a table to be imported for R as matrix or data.frame but I first need to edit it because I've got several lines with the same identifier (1st column), so I want to sum the each column (2nd -nth) of each identifier (1st column)
The input is for example, after sorted:
K00001 1 1 4 3... (8 Replies)

seek
seek(n) Tcl Built-In Commands seek(n)
__________________________________________________________________________________________________________________________________________________NAME
seek - Change the access position for an open channel
SYNOPSIS
seek channelId offset ?origin?
_________________________________________________________________DESCRIPTION
Changes the current access position for channelId. ChannelId must be a channel identifier such as returned from a previous invocation of
open or socket. The offset and origin arguments specify the position at which the next read or write will occur for channelId. Offset must
be an integer (which may be negative) and origin must be one of the following:
start The new access position will be offset bytes from the start of the underlying file or device.
current The new access position will be offset bytes from the current access position; a negative offset moves the access position back-
wards in the underlying file or device.
end The new access position will be offset bytes from the end of the file or device. A negative offset places the access position
before the end of file, and a positive offset places the access position after the end of file.
The origin argument defaults to start.
The command flushes all buffered output for the channel before the command returns, even if the channel is in nonblocking mode. It also
discards any buffered and unread input. This command returns an empty string. An error occurs if this command is applied to channels
whose underlying file or device does not support seeking.
Note that offset values are byte offsets, not character offsets. Both seek and tell operate in terms of bytes, not characters, unlike |
read.
