in the same concept, how can i extract all the substring starting with example input (remember, the input content is in one line):
10120

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

Thanks

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

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)

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…
user=bhavya
signature={sdfghjklsdfghjklzxcvbnmghjkdfghjkzxcvbnmzxc}

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.

Thanks

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.

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

sed -e "s/.*FOO//;s/BAR.*//" test.txtFor example:
echo "Test to find string between words FOO-/*+_and_+*/- BAR" | sed -e "s/.*FOO//;s/BAR.*//"

Hello,
What if I have a txt like this:
Begin
yyyy
yyyy
End
…….
Begin
xxxx
xxxx
End

what if I want to display the text between “begin” and “end” but only for the first sequence, or only for the 2nd or 3rd?
Thanks a lot.

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

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.

Example:

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

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

Any Idea how to do this?

Cheers.

Hi,
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.

Begin
line1
line2
End

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 ?

Thanks
