View 2 Replies View RelatedA function by name abc is called in many files. I want to copy all the lines with the function call to an output file.A simple grep on function name doesn't help me as the function call is spanning across multiple lines as follows:
abc(parameter1,
parameter2,
parameter3);
So I want to copy all the three lines (till semicolon) to the output file.The problem is because there are more than 200 calls for the same function and I cannot do it manually
I want to replace a pattern with other pattern in a textfile. But there are two same patterns,but I need two change only the second occurence. EG:
Text file is
aaaa=1
bbbb=2
cccc=3
dddd=4
[code]....
Now I want to change aaaa=x into some other entry.
Just using shell scripting, how can I insert text into the middle of a file name. The file has a predictable pattern, let's say 3 letters and 3 numbers and I want to insert text in the middle of those 2 patterns. Say ABC123 is the file name. As a result, the file name should be ABC.blah.123

I have a file which contains milion of records. It contains 12 columns seperated by "||" (delimeter).
First two fields contain first name and last name of a person. Now my requirement is to delete all those records from this file for which:
First two fields does not contain any alphabet.
For e.g i have below mentioned records in file:
gaurav||gandhi||123||456||789
#a%bcd||123abc||89|90||91
12345||@@@||89||123||234
***||!!!!||98||76||90
Now, last two lines should be removed from this file since first two fields does not contain any alphabet for these two records.
I have such a file(test.txt):
abc 123 456
abc 256 145

I want to append some text to the file, files are mostly big, more then 100 mb. I found the cat command, so I can create a new txt file and then append it to the original file with it. Two questions:
1. Can I append text to the file instead of creating the new file and then appending it to the original file? eg:
Code:
cat file.avi "some text" > newfile.avi
2. cat takes several seconds to execute the merging files together, it seems that it is reading the original file first, is there a way skip the reading and just append the file?
Say I have a text file like:
Code:
1
3
4
How would I use ksh to put the number '2' into the second line of that file?Okay it's not bash, it's ksh because this computer is OpenBSD

may be an advanced question but I need to know how to do this. Here at work I am in charge of recruiting and we have about 1,000 resumes in already. All of the resumes are in a .pdf format. I need to rename every .pdf in the following format:{firstnameLastname}.pdfThe only way I know how to do this is to convert all the .pdf files to text, extract the name out of the first few lines of text, import into excel, and then use VBA to rename the files in mass:Here is my logic so far:~Deskop/a = houses all the .pdfresumesOpen terminal: Code: cd ~/Desktop/afor f in *.pdf; do pdftotext -raw $f; done That will convert all of the preceding resumes into text filesNow I would like to append the name of the text file into the last line of the text file. So, for example, for Resume1.txt, I want to append "Resume1.txt" to the last line within Resume1.txt. So after I run the command I open Resume1.txt and on the last line within I want to see "Resume1.txt" on the last line, at the end of the resume.How can I do this? I would like to use a loop and have the terminal append the filename to the body of the text file until all of the have been appended.

View 3 Replies View RelatedHow do you append text to an entry in an existing file? For example, lets say I have a file called "env.logon" in /home/myself/bin that contains the following text:
PATH=/bin:/sbin If I wanted to add, via command line, ":/usr/bin:/usr/sbin" to the PATH= and I
used the "echo" command (echo "PATH=:/usr/bin:/usr/sbin) it would create a second entry and my file would look like:
PATH=/bin:/sbin
PATH=:/usr/bin:/usr/sbin
What I want is for it to look like:
PATH=/bin:/sbin:/usr/bin:/usr/sbin
Is there a way to get this result via command line?
I am thinking of appending something to each line in a text file with Java. I prefer not write a new file with content appended from the old one.That 'something' would probably be Time Stamp when the file is created (which is same for each line).I am not sure Java provide some easy way for it or not

eed to make a script to append a line to the bottom of multiple files (only certain files, but 100's spread over directories).Doing a find replace inside multiple files is easy, I use the followingfind /base/dir -name "*.txt" -exec perl -pi -w -e 's/FIND/REPLACE/g;' {} ;So I tried doing the followingfind /base/dir -name "*.txt" -exec echo "Append this" >> {} ;However this just appends all the text into a file called "{}". Whereas {} should be replaced with each file that's found.

got the same thing in terms of a u: number but the issue is I need to remove duplicates and just leave one and the file has multiple duplicates of different u: numbers and it's 14,000 lines long. can anyone tell me if I can use awk? sed? or sort for something like this to? removing lines that have a certain string in there that's a duplicate.
How do yo find a pattern with sed or awk and then:
- add a # at the beginning of the line containing it
- and add a # at the beginning of the following 2 lines, too?
Say, I want to comment out the line containing "which 0launch" and the two lines following it:
if [ -x "`which 0launch`" ]; then
exec 0launch http://rox.sourceforge.net/2005/interfaces/ROX-Filer -S
fi
Expected result:
#if [ -x "`which 0launch`" ]; then
# exec 0launch http://rox.sourceforge.net/2005/interfaces/ROX-Filer -S
#fi
I need this because I do not want to comment out every line containing "fi", just the "fi" of this specific if statement.
I have to use sed with this problem, and sed is extremely complicated, they could probably teach a whole class on this entire function.
Here's an example to show what I need to do:
Code...
how would I say that every line before I reach the first match of "sweet" should be deleted so that the output will look like: Code...
I have 8 files, and each contains around 2000 lines. I want to search the particular word in these files between line number 1500 to 2500.
The output should look like:

sample_2.txt :
1610:declare var testing
sample_7.txt :
1610:declare var testing
sample_10.txt :
1710:declare var testing
Is it possible to use grep for this task?
I have a file called test.
