#vi file1.txt
123456 aaa 54

#vi file2.txt
1456456 bbb 452

#vi file3.txt
667766 ccc 123

like above , file1.txt have aaa , file2.txt have bbb , file3.txt have ccc , I would like to sort it out , to output a file (matching.txt) that match the file name with the character as below .

#vi matching.txt
aaa file1.txt

You could do something like:

while read line; do

fgrep -q "$line" $filelist

if [ $? -ne 0 ]; then

echo "$line does not appear"

done < master.txt

Where $filelist contains the names of the files you want to search.

If you know the names, you can just list them:

filelist="file1.txt file2.txt file3.txt"

If you just want to hard code them, you can also do that. Or you can find patterns:

filelist="file*.txt"

>if I just would like to list out the line (in the master file) that do not appear in any files

This should do it:

while read line; do

fgrep -q "$line" file*.txt

if [ $? -ne 0 ]; then

echo "$line"

done < master.txt

thanks for Dennis Handly , you help a lot.

May be I was not express my requirement clearyly and I would like to change a bit requirement .

I have a file as below ( eg. master.txt) , it delimited by " and space

#vi master.txt
""""""""" aaa bbb ccc ddd eee " " "
""""""""" xxx yyy zzz mmm ooo " " "
""""""""" ggg hhh iii jjj kkk " " "

I also have a set of files (eg. file1.txt , file2.txt ... ) .

what I would like to do is to list the lines that do not appear the fourth column ( ddd , mmm , jjj ) of master.txt in any files, that mean search ddd , mmm , jjj in all .txt file ,if do not appear , then output the line.

Assume mmm , jjj is not appear in any .txt file , then output the below result.

""""""""" xxx yyy zzz mmm ooo " " "
""""""""" ggg hhh iii jjj kkk " " "

can advise how I can do for it ?

>May be I did not express my requirement clearly

Did you try it?

>I have a file as below, it delimited by " and space

""""""""" aaa bbb ccc ddd eee " " "

Can you explain how the double quote is delimiting things?

As far as the shell's read is concerned (with the default IFS), there are these 9 fields:

""""""""", aaa, bbb, ccc, ddd, eee, ", ", "

>I would like to do is to list the lines that do not appear the fourth column (ddd, mmm, jjj) of master.txt in any files

Try:

while read f1 f2 f3 f4 f5 f6 f7 f8 f9; do

fgrep -q "$f5" file*.txt

if [ $? -ne 0 ]; then

echo "$f1 $f2 $f3 $f4 $f5 $f6 $f7 $f8 $f9" # print an approximation of original line

done < master.txt

Thanks , it should be works

May I ask
1) what is the use of f1 , f2 .... ? is it represent " ?
2) what is the mean of "$f5

If you are happy with the answers, please click on the Kudos stars of each answer that was helpful.

>1) what is the use of f1, f2 ...? is it represent?

Since I don't know what your fields means, I just assigned short variable names, they just mean field1, etc.

>2) what is the meaning of "$f5?

This provides the value of the variable f5, field5.

thx replies,

I am sorry that when I apply it to my real case , it still have problem , as in my real case , the master file has a bit difference Dennis Handly 's method is delimited by space only ( f1 f2 f3 is delimited by space ) , the real file is a bit complicate.

The below is the master file of the real case , in the string (eg. aaa bbb ccc ddd eee) , there are other space before this string .

#vi master.txt
"ffd" hg " gg"""""" aaa bbb ccc ddd eee " " "
"fd "jg "" """"" xxx yyy zzz mmm ooo " " "
"hdgd"jg"""fd""f"" ggg hhh iii jjj kkk " " "

I want to compare ( in my master file ) is

1) after 9 " , then
2) the 4th column of the string that delimited by space ,

can advise what can i do ?

thx

I may be make it confued so I would like to clearly re-post my question .

I have a master file , the content is as below.
#vi master.txt
"d"""""""" aaa bbb ccc ddd eee " " "
"""y""d"""" xxx yyy zzz mmm ooo " " "
""f""""""" ggg hhh iii jjj kkk " " "

I also have some text files ,
eg.
#vi file1.txt
aaa
#vi file2.txt
bbb
#vi file3.txt
ccc
#vi file4.txt
ddd

I would like to check if the fourth column ( eg. ddd mmm jjj ) is exist in these text files , if not exist , then output this line , in this case , output the below ( as ddd exists in file4.txt )
"""y""d"""" xxx yyy zzz mmm ooo " " "
""f""""""" ggg hhh iii jjj kkk " " "

The requirement is check
1) after 9 " , and
2) the 4th column of the string that delimited by space .

can advise what can I do ? Thanks

Ok, try this:

while read line; do
   IFS_save=$IFS
   IFS='"\n'    # split on double quote
   echo "$line" | read f1 f2 f3 f4 f5 f6 f7 f8 f9 f10 f11
   IFS=$IFS_save
   f10=${f10# *} # strip leading spaces
   f10=${f10% *} # strip trailing spaces
   echo "$f10" | read f1 f2 f3 f4 f5 # split on spaces
   fgrep -q "$f4" file*.txt
   if [ $? -ne 0 ]; then
      echo "$line" # print original line if field not found
   fi
done < master.txt
