How I can change the fifth column of these rows

Question

[hosin]

I have many many rows (about 6000) from PennCNV software, icludes 7 columns , like these:

chr10:70920533-70921956       numsnp=3      length=1,424       state1,cn=0 WDS1_1.adjusted startsnp=oar3_OAR10_70920533 endsnp=oar3_OAR10_70921956
chr15:2694950-2706055         numsnp=4      length=11,106      state1,cn=0 WDS1_1.adjusted startsnp=oar3_OAR15_2694950 endsnp=oar3_OAR15_2706055
chr20:25669233-25685291       numsnp=5      length=16,059      state5,cn=3 555individual555.new.adjusted startsnp=oar3_OAR20_25669233 endsnp=oar3_OAR20_25685291
chr20:25876183-25899904       numsnp=8      length=23,722      state5,cn=3 555individual555.new.adjusted startsnp=oar3_OAR20_25876183 endsnp=oar3_OAR20_25899904

So how I can change the fifth column, like :

chr10:70920533-70921956       numsnp=3      length=1,424       state1,cn=0 1v startsnp=oar3_OAR10_70920533 endsnp=oar3_OAR10_70921956
chr15:2694950-2706055         numsnp=4      length=11,106      state1,cn=0  2v startsnp=oar3_OAR15_2694950 endsnp=oar3_OAR15_2706055
chr20:25669233-25685291       numsnp=5      length=16,059     state5,cn=3 3v startsnp=oar3_OAR20_25669233 endsnp=oar3_OAR20_25685291
chr20:25876183-25899904       numsnp=8      length=23,722     state5,cn=3 4v startsnp=oar3_OAR20_25876183 endsnp=oar3_OAR20_25899904

Hello,

you can do it with awk:

$ awk -v OFS="\t" '{print $1, $2, $3, $4, NR"v", $6, $7}' input.txt
