$(find A -type f) produces a list of files in the directory A.
${file/A/} produces the file name with the leading "A" deleted,
eg:"A/foo" becomes "/foo"
$file B/${file/A/} becomes "A/foo B//foo" which is the
argument list to diff.
I tried your script in little modified wayas follows
rm -f temp;for file in $(find datafiles -type f); do if test $(diff $file
datafiles2/${file/datafiles/} | wc -l) -gt 5; then echo $file >> temp; fi;
done
where directories compared are datafiles and datafiles2
it gave output of
[EMAIL PROTECTED]:~$ cat temp|wc -l
1113
Files in datafiles are
[EMAIL PROTECTED]:~$ ls -l datafiles/* |wc -l
1131
But using diff and diffstat as
diff datafiles datafiles2 >difffile
diffstat -v -t difffile -o diffsum
[EMAIL PROTECTED]:~$ cat diffsum| sed "/^5,/d"|sed "/^4,/d"|sed "/^3,/d"|sed
"/^2,/d"|sed "/^1,/d"
INSERTED,DELETED,MODIFIED,FILENAME
816,816,0,BOSCHCHASY
739,739,0,MAX
833,833,0,MIRZAINT
267,267,0,NANDAN
812,812,0,SUVEN
Have I misunderstood you in using your script?
Instead of cat diffsum| sed "/^5,/d"|sed "/^4,/d"|sed "/^3,/d"|sed
"/^2,/d"|sed "/^1,/d",
I tried
while read INSERTED DELETED MODIFIED FILENAME;do if [ $INSERTED -gt 5 ];then
echo $FILENAME;fi;done < diffsum
I get error
bash: [: 5,5,0,3IINFOTECH: integer expression expected
I also tried
for line in $(cat diffsum|sed "/FILENAME/d");do insert=$(echo $line|cut -d,
-f1);symbol=$(echo $line|cut -d, -f4);if [ insert -gt 5 ];then echo
$symbol;fi;done
Still I got
bash: [: insert: integer expression expected
What to do to correct these errors.
