Hi friends, I just want to try some thing with shell using loop and counter
I have 30 Directory, in each directory number of files say 5, 10, 20 etc…
Code:
directory_1
directory_2
directory_n
what I want to do is read files from directory_1 say 5 files
if my counter is like this
Code:
m=2000 # M is for folder
n=1 # N is for file counter
for file in `ls *.dat |sort -t"_" -k2n,2`; do
awk -F, 'FNR == 1{print '$m',$1,$2,$3,'$n',$5,$6,$7}' OFS="," $file >>file.csv
n=$(( $n+1 ))
done
output wanted is something like this in single file comma separtated
Code:
column 1 column 2 $1 $2 $3 $..........$7
2000 1
2000 2
2000 3
2000 4
2000 5
2001 1
2001 2
2002 1
How can I use another counter in my script, also it has to read files from directory_1, directory_2 ….directory_n
Note : directory names are same only after
Code:
_
number is changing
so I think for this also one more counter is needed
Code:
something like this
x=1
cd directory_'x'
awk script
cd ..
increment x
cd directory_'x' # 2nd directory
awk script... so on
