To replace the content of the first column with "":

Code:
awk 'BEGIN{FS=OFS="\t"}{$1="";}1' file

To remove the first column and the first fieldseparator:

Code:
awk 'BEGIN{FS=OFS="\t"}{$1="";sub("\t","")}1'  file

Tools Need to chose other cut option
try with the c option, as in
Code:
ls | sort | cut -c2-

which will display all your filenames, sorted, but then the first character removed

Replace first column with spaces:
Code:
awk '{gsub(/./," ",$1)}1' OFS="\t" infile

Empty first column:
Code:
awk '{$1=""}1' OFS="\t" infile

Delete first column:
Code:
sed 's/^[^\t]*[\t]//' infile

Code:
cut -f2- infile
