Yes, there is:

Code:
i=1
while (( i<=20 ))
do
    grep 'something' -w file$i |
    awk -v OFS='\t' '{ print $1,$15,$4,$4,$4,$4,$2,$3,$4,$4 }' |
    sed -e 's/[+-]/U0/2' -e 's/[+-]/0/2' -e 's/[+-]/0/2' -e 's/[+-]/0/2' -e 's/+/F/1' -e 's/-/R/2' -e 's/[+-]/../2' -e 's/chr//1' > new.file$i
    (( i=i+1 ))
done

Hi, I'm getting a new error and I can't seem to understand why.

'/convert.sh: line 2: syntax error near unexpected token `do
'/convert.sh: line 2: `do

Code:
for f in file1 file2 file3
do
    awk -v OFS='\t' '{ print $1,$15,$4,$4,$4,$4,$2,$3,$4,$4 }' $f |
    sed -e 's/[+-]/U0/2' -e 's/[+-]/0/2' -e 's/[+-]/0/2' -e 's/[+-]/0/2' -e 's/+/F/1' -e 's/-/R/2' -e 's/[+-]/../2' -e 's/chr//1' > $f.new
done

Not sure what's going on?

use code like:-
t=`ls -l |wc -l`
total=`echo "$t -1"|bc`
while [ $total -le 1 ];
do

steps to do;
$total=`"echo $total -1"|bc`
done

thanks for replying.

I got this error when I copied your code
Quote:
./test: line 8: syntax error near unexpected token `done'
./test: line 8: `done'
I copied only
Code:
t=`ls -l |wc -l`
total=`echo "$t -1"|bc`
while [ $total -le 1 ];
do

steps to do;
$total=`"echo $total -1"|bc`
done

The "steps to do" was meant as a "fill in the blank" comment, I guess.

The use of ls -l if you don't actually use the long format for anything is obviously Useless. Fixing that also removes the need to remove the "total" line from the sum.

But anyway, if you don't use the count for anything, either, just loop over the file names.

Code:
for file in *; do
  # stuff
done

Tangentially, I guess RahulJoshi really meant -ge rather than -lt

Okay, so is the error I'm getting in post #10 above because of a formatting issue? I'm not sure I understand what is going on. It was working before then it's not???

Is there a way for me to trouble shoot this?

rm files in a directory, looping, counting, then exit

I am trying to write a script that will look for a file in a directory, then remove it. I need it to loop until it has removed a certain number of files. Is it better to do a repeat or to list each file in a pattern? Files will be numbered like RAF.01.*, RAF.02.*, etc. Thanks, James (6 Replies)
