Sed Find and Display Text Between Two Strings or Words

Q. How do I find the text between the strings FOO and BAR inclusive using sed command line option?

A. Sed is a stream editor. A stream editor is used to perform basic text transformations on an input stream – a file or input from a pipeline.

To output all the text from file called test.xt’ between ‘FOO’ and ‘BAR’, type the following command at a shell prompt. The -n option suppress automatic printing of pattern space:
$ sed -n '/WORD1/,/WORD2/p' /path/to/file
$ sed -n '/FOO/,/BAR/p' test.txt

You can easily find out all virtual host entries from httpd.conf, type
# sed -n '/<VirtualHost*/,/<\/VirtualHost>/p' /etc/httpd/conf/httpd.conf

    This is just what I’ve needed! I’ve been playing with awk these days, trying to do the same. As these are my first steps in text manipulation field, I’d appreciate if you could help me out with problems I’ve encoutered: e.g. I want to print only the substring between two words/strings and not those two words/strings (the command you gave prints WORD1 and WORD2, and I do not want them to be printed at all); I believe it’s possible to do some search&replace after I run the above sed command, but I wonder if it’s possible to be done through only one iteration; secondly, let’s say I have two files with different strings, where each string is in its own line in the file; what I want to do is to append each string of the second file to the first so that I could have a file formatted like this:
    first_file’s_string1, second_file’s_string1
    first_file’s_string2, second_file’s_string2

    I couldn’t find a way to do this no matter what I’ve tried. Can someone help me with this? Would appreciate a lot!

    , is a range operator in sed – its very useful. I think it can be used to specify 2 line numbers and it will return all the lines between those 2 lines.

  • nixCraft April 14, 2008, 7:49 pm

    Yes, it is a range operator; if you know line number it is good; but most time you need to select data using dynamic conditions

  • gameboy April 22, 2008, 11:05 am

    thanks it’s a good tips !!
    I notice a little mistake in your regular expression :
    means <VirtualHost with 0 t or an infinite t

    It will be better :

    see ya

  • Gagan Brahmi May 5, 2008, 2:12 am

    A better option will be use to ‘space’ after VirtualHost string in order to ensure that we get the VirtualHost having some value against it.

    For example:-

    # sed -n ‘/<VirtualHost /,//p’ /etc/httpd/conf/httpd.conf

    i have a file like this:

    ther: Part II (1974) …. Vito Corleone
    … aka Mario Puzo’s The Godfather: Part II (USA: complete title)
    # Mean Streets (1973) …. Johnny Boy
    # Bang the Drum Slowly (1973) …. Bruce Pearson
    # The Gang That

    I need to delete all between ‘)’ and the ‘#’ (keep the # start of each line as is)

    ther: Part II (1974)
    # Mean Streets (1973)
    # Bang the Drum Slowly (1973)
    # The Gang That

    how do i do it?

  • codegazer May 1, 2009, 12:48 am

    Have been reading your blogs for quite some time now and are very informative.
    On this particular script, I need some advice. Say I have 2 words, Begin and End that I am looking for in a file. For Ex.


    I am trying to modify your script. I want to delete what lies between these 2 patterns viz. Begin/End but I need to keep the words Begin and End. I end up deleting those as well.

    Any inputs ?


  • sedbeginner May 14, 2009, 11:25 pm

    I have a similar problem, I have a long line of text and within this line I have my start and end variable and I need the text between start and end.


    t6gd68g d9d8j5%9j30j 0jf087*(&&^*2hd920STARTid8 =e72920 2d9nf9END93nf300j90

    needed output between START and END, resulting in id8 =e72920 2d9nf9

    Any Idea how to do this?


    • Vasileios Sotiras September 9, 2012, 9:06 pm

      $ echo ‘t6gd68g d9d8j5%9j30j 0jf087*(&&^*2hd920STARTid8 =e72920 2d9nf9END93nf300j90’ | sed -n ‘s/.*START//;s/END.*//p’
      id8 =e72920 2d9nf9

      • pawlx0r October 17, 2012, 6:27 am

        Life saver! I’ve been trying to figure that out forever.

        Since it helped me, I guess I can add that if you have to grab text between two directories in a path like:

        /directory1/blablablabla/directory2/ and all you want is blablablabla
        Your code is perfect, and all you have to do is change the /’s to something else so that you can use /’s in the text, I used % –such as:

        sed -n ‘s%.*directory1/%%;s%/directory2.*%%p’

        I hope this helps someone else.

    Hi there,
    I got some problem.
    I got this html Code:

    1 neue Nachricht

    And need to extract the Text “1 neue Nachricht” – but that thing can change.
    Any way in doing this by sed?


  • Nico Maas June 17, 2009, 7:24 am

    I meant this Code:

    a href=”../messages/index.php” class=”navilink”>1 neue Nachricht

  • Robsteranium June 17, 2009, 2:18 pm

    You may find that a web scraper using xpath is more appropriate for extracting data from web pages. Try ScRubyt!

    I found a similar command. Here the strings at both ends (FOO and BAR) will be ignored.

    sed -e "s/.*FOO//;s/BAR.*//" test.txt
    For example:
    echo "Test to find string between words FOO-/*+_and_+*/- BAR" | sed -e "s/.*FOO//;s/BAR.*//"
    • Sumod March 25, 2015, 5:05 am

      this code is working for me.but the issue is in the text file ,4 the line have no specific pattern as the above sentences. This text file is an output of another shell script.i need to exclude the 4th lin efrom the text file.is there any way to achieve this?

  • John May 18, 2011, 8:41 pm

    For some reason none of listed example does not working properly when trying to search for ,no matter which command is applied it always show rest of content in file.Could be because second word in search is and that causing problem for some reason.But i managed to make it work by this command:
    sed -n ‘s//&/p’ index.html
    It shows entire line where is located,but that is not problem,since the key was to find out content between and tag.

  • bhavya December 5, 2011, 8:07 pm

    Hi ,
    There are some problems I am facing with linux right now.

    This is what I am doing to generate a cryptographic signature fron bash script….

    step1. I encrypt a text : encrypt(bhavyakailkhurabhavyakailkhura) and get a encrypted string sdfghjklsdfghjklzxcvbnmghjkdfghjkzxcvbnmzxc.
    step2. I copy that string manually from mouse no commands used and append it with a file..

    $ cat textfile.txt…

    step3. Using “sed” on text file I send text between “{” and “}” to another file bhavya.txt
    step4. now when I try to decrypt bhavya.txt it say error in reading file. I checked the text is same as encrypted. When I copy original encrypted text in step 1 and decrypt It works.

    I think the problem is sed command changes spacing between text its not same as copying using mouse. Do you have any idea how we can solve this problem?

    Sorry for clumsy and lengthy explanation.


    • j0hny December 10, 2011, 9:06 pm

      when using sed try to add some tr commands… eg. sed | tr -d’ ‘ | tr -d’\n’ | tr -d’\t’

      this will delete all spaces, newlines etc that sed might add to your string

      to check the spacing you can try: cat file.txt | od -c (find the delimiter), use sed as regulary (when it fails), cat new_by_sed_created_file.txt | od -c (check the changes)

    • j0hny December 10, 2011, 9:10 pm

      sorry, should be: sed | tr -d ‘ ‘ | tr -d ‘\n’ | tr -d ‘\t’

    in the same concept, how can i extract all the substring starting with <ds:include and ending with .xml from a long textual string?
    example input (remember, the input content is in one line):

    expected output:
    ds:include ds:uri=”$HOME/lookup/lookup_table.xml
    ds:include ds:uri=”$HOME/trans/transform.xml
