Removing letters after a certain character within a range of columns
Hi there,
I am trying to remove al letters after : character on specific columns from 10th column till 827. I used sed and cut to do so but I am sure there is better one liner someone can think of from unix community members.
Huge file but it has this structure (Total number of Columns = 827, rows = 605278)
Code:
#CHROM POS ID REF ALT QUAL FILTER INFO FORMAT Control1 Control2 Case1 Case2
chr1 65872 . T G 2480.51 . AC=65;AN=92;SF=0,1;VRT=1 GT:GQ:DP:AD:PL 1/1:3:243:176,66:27,3,0 0/1:21:148:135,13:21,0,21 0/1:9:250:201,49:9,0,115 .
chr1 65893 . G A 433.77 . AC=7;AN=10;SF=0,1;VRT=1 . . 0/1:173:144,29:198,0,91:91 0/1:143:100,43:180,0,233:99
I am trying to get this structure
Code:
#CHROM POS ID REF ALT QUAL FILTER INFO FORMAT Control1 Control2 Case1 Case2
chr1 65872 . T G 2480.51 . AC=65;AN=92;SF=0,1;VRT=1 GT:GQ:DP:AD:PL 1/1 0/1 0/1 .
chr1 65893 . G A 433.77 . AC=7;AN=10;SF=0,1;VRT=1 . . 0/1 0/1
Hi all,
I have a variable, on some machines it is '1024', which is fine, but on others it is '1024Mb' etc. I need this variable to simply be '1024', does anyone know how I could ensure this is always the case? Perhaps a command to remove any letters/characters that aren't integers if there is... (3 Replies)

Hi all,
Disclosure: I am very new to Unix, but eager to learn..
I've been tasked with transferring logs to a remote server. After I've verified these logs have transferred correctly I have to remove the source files. The naming scheme is:
/directory/2012.05.01

Hi,
I want to remove trace files in a particular directory for a specific date range. Currently i can remove based on time (e.g find /path/*.trm -mtime +1000 -exec rm {} \;). But i want to remove .trm files within a date range. E.g to remove .trm files between jan 1 2002 to April 15 2005.

In each line of file, I wish to check if word1 is a non-connected subset of any of the other words in the line. If yes, keep only the words that ward1 is a subset of. Else, remove the whole line.
Also, I want to remove the letters that word1 doesn't match with, except for "_+"

rgb2pct
rgb2pct(1) General Commands Manual rgb2pct(1)NAME
rgb2pct - rgb2pct.py Convert a 24bit RGB image to 8bit paletted
SYNOPSIS
rgb2pct.py [-n colors | -pct palette_file] [-of format] source_file dest_file
DESCRIPTION
This utility will compute an optimal pseudo-color table for a given RGB image using a median cut algorithm on a downsampled RGB histogram.
Then it converts the image into a pseudo-colored image using the color table. This conversion utilizes Floyd-Steinberg dithering (error
diffusion) to maximize output image visual quality.
-n colors:
Select the number of colors in the generated color table. Defaults to 256. Must be between 2 and 256.
-pct palette_file:
Extract the color table from palette_file instead of computing it. Can be used to have a consistant color table for multiple files. The
palette_file must be a raster file in a GDAL supported format with a palette.
-of format:
Format to generated (defaults to GeoTIFF). Same semantics as the -of flag for gdal_translate. Only output formats supporting
pseudocolor tables should be used.
source_file:
The input RGB file.
dest_file:
The output pseudo-colored file that will be created.
NOTE: rgb2pct.py is a Python script, and will only work if GDAL was built with Python support.
EXAMPLE
If it is desired to hand create the palette, likely the simpliest text format is the GDAL VRT format. In the following example a VRT was
created in a text editor with a small 4 color palette with the RGBA colors 238/238/238/255, 237/237/237/255, 236/236/236/255 and
229/229/229/255.
