txt file modification which is beyond me
Dear all,
I 'd like to create a new txt file using the old file. For example, in old file, if count=2 then in new file, repeat that row twice, with the only difference is: on the first row, 'start' column contains the 1st apart of the 'start' in the old file; while in the 2nd row, the 'start' column contains the 2nd part of the 'start' coulmn in the old file.
Thanks a lot!
old file example:
chr gene_name count start
1_q OMA1 2 43210,243007,
1_q TFR1 3 429310,2412007,23366,
1_q FTOMA1 5 3290,243317,24333,2433136,24334,
...
new file I want:
chr gene_name count start
1_q OMA1 2 43210
1_q OMA1 2 243007
1_q TFR1 3 429310
1_q TFR1 3 2412007
1_q TFR1 3 23366
1_q FTOMA1 5 3290
1_q FTOMA1 5 243317
1_q FTOMA1 5 24333
1_q FTOMA1 5 2433136
1_q FTOMA1 5 24334

colrm
COLRM(1) BSD General Commands Manual COLRM(1)
NAME
colrm -- remove columns from a file
SYNOPSIS
colrm [start [stop]]
DESCRIPTION
The colrm utility removes selected columns from the lines of a file. A column is defined as a single character in a line. Input is read
from the standard input. Output is written to the standard output.
If only the start column is specified, columns numbered less than the start column will be written. If both start and stop columns are spec-
ified, columns numbered less than the start column or greater than the stop column will be written. Column numbering starts with one, not
zero.
Tab characters increment the column count to the next multiple of eight. Backspace characters decrement the column count by one.
ENVIRONMENT
The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of colrm as described in environ(7).
EXIT STATUS
The colrm utility exits 0 on success, and >0 if an error occurs.
SEE ALSO
awk(1), column(1), cut(1), paste(1)
HISTORY
The colrm command appeared in 3.0BSD.
