I have a large text-file with tab-delimited genetic data that looks like:
KSC112 KSC234 0 0 1 1 A G C T
I simply wan to delete the first column, but since the file has 600 000 columns, it is not possible with awk (seems to be limited at 32k columns).
Does anyone have an idea how to do this? (2 Replies)
Hello,
I am trying to parse a file that resembles the last three groupings into something looking like the first two lines. I've fiddled with sed and awk a bit, but can't get anything to work properly. I need them separated by some delimiter. The file is some 23,000 lines of the stuff....

I'd like to take the output of `pwsafe --exportdb > database.txt` and convert it to a KeePassX XML friendly format (feature request in pwsafe).
I found flat file converter but the syntax is beyond me with this example. Solutions are welcomed.
More details
Here is the pwsafe --> KeePassX XML... (2 Replies)

fspec - format specification in text files
DESCRIPTION
It is sometimes convenient to maintain text files on the system with non-standard tabs, (tabs that are not set at every eighth column).
Such files must generally be converted to a standard format, frequently by replacing all tabs with the appropriate number of spaces, before
they can be processed by system commands. A format specification occurring in the first line of a text file specifies how tabs are to be
expanded in the remainder of the file.
A format specification consists of a sequence of parameters separated by blanks and surrounded by the brackets <: and :>. Each parameter
consists of a keyletter, possibly followed immediately by a value. The following parameters are recognized:
ttabs The t parameter specifies the tab settings for the file. The value of tabs must be one of the following:
o A list of column numbers separated by commas, indicating tabs set at the specified columns.
o A '-' followed immediately by an integer n, indicating tabs at intervals of n columns.
o A '-' followed by the name of a ``canned'' tab specification.
Standard tabs are specified by t-8, or equivalently, t1,9,17,25, etc. The canned tabs that are recognized are defined by
the tabs(1) command.
ssize The s parameter specifies a maximum line size. The value of size must be an integer. Size checking is performed after tabs
have been expanded, but before the margin is prepended.
mmargin The m parameter specifies a number of spaces to be prepended to each line. The value of margin must be an integer.
d The d parameter takes no value. Its presence indicates that the line containing the format specification is to be deleted
from the converted file.
e The e parameter takes no value. Its presence indicates that the current format is to prevail only until another format
specification is encountered in the file.
Default values, which are assumed for parameters not supplied, are t-8 and m0. If the s parameter is not specified, no size checking is
performed. If the first line of a file does not contain a format specification, the above defaults are assumed for the entire file. The
following is an example of a line containing a format specification:
* <:t5,10,15 s72:> *
If a format specification can be disguised as a comment, it is not necessary to code the d parameter.
