Deleting a column in multiple files that are comma separated
Hi,
I have a directory that contains say 100 files named sequencially like input_1.25_50_C1.txt
input_1.25_50_C2.txt
input_1.25_50_C3.txt
input_1.25_50_C4.txt
..
..
..
input_1.25_50_C100.txt
an example of the content in each of the file is:
"NAME" "MEM.SHIP"
"cgd1_10" "cgd1_10" 0.938962779873022
"cgd1_1860" "cgd1_1860" 0.728179501334915
"cgd1_2500" "cgd1_2500" 0.751709755780061
"cgd1_2560" "cgd1_2560" 0.8086690400501
"cgd1_2640" "cgd1_2640" 0.750586302165714
"cgd1_2800" "cgd1_2800" 0.954020921349781
"cgd1_290" "cgd1_290" 0.757355995574881
"cgd1_2950" "cgd1_2950" 0.558344549451538
"cgd1_3010" "cgd1_3010" 0.667420188529345
"cgd1_50" "cgd1_50" 0.545172222953814
"cgd2_1000" "cgd2_1000" 0.944926355001402
"cgd2_1690" "cgd2_1690" 0.861817882469458
"cgd3_1820" "cgd3_1820" 0.817150133730118
"cgd3_2150" "cgd3_2150" 0.553855831143878
"cgd4_2220" "cgd4_2220" 0.577452218116135
I want to delete the second & third column of each file, make the file tab delimited and replace the column heading "NAME" in the first column as [Gene]
Is there a way in awk or shell programming to do this at a directory level; without openning each file and editing it.
Please let me know.

I would like to copy 2 parts of a csv file from Unix to an XL sheet. However to save time I do not want to format the column ever time I cut and paste into XL(Text2Column). I've used awk -F, '{Print $1, $2....}'. Is there a script or code that can automatically format the csv for XL columns?
