file format exchange question

Pacific Yan

Hello, could somebody help me to write a shell script (no PERL or Java) to change the the file format from file 1 to
file 2?

file 1:

CASP1, CASP2, CASP3, CASP4, CASP5, CASP6, CASP7, CASP8, CASP9, CASP10, CASP13, .......



file 2:


CASP1
CASP2
CASP3
CASP4
CASP5
CASP6
CASP7
CASP8
CASP9
CASP10
CASP13
......



Thanks,

1. 
   
2. $ sed 's/, /\
   
3. > /g' file1

对了，上面两行最前面的$和>是提示符

bjgirl

$cat file1|tr "," "\n" >file2

Thank you all!

Now I will see how neat the shell scripts are comparing to my following PERL script.


my perl script:
#!/usr/bin/perl -w
$file="your path for file 1";
open(FILE, $file) or die "err: $!\n";
while(<FILE> {
chomp;
my @line=split /, /, $_;
for ($i=0; $i<$#line; $i++)
{
print "$line[$i]\n";
}
}
close (FILE);

awk -F"," '{for(i=1;i<=NF;printf"%s\n",$i++)}'  file

Now I will give you a very neat perl script can be excuted by entering a command:

1. 
   
2. perl -e 'while (<>){ s/,/\n/g; print $_;}' OLD_FILE > NEW_FILE
