I have a mail.log file, of which I want to redirect only the search strings of the sender from=<example.sender@exampledomain.com> and the size size=4537 to a file.
In every case the sender string starts as from=<> and the size string starts as size=
What would be the grep command to redirect only the two search strings to a .txt file?
how to search for those files which contain word "AM_COLLECTION=22". I need to know all the files with this string. ( I know the grep command can do it but either

I tested cding to the folder and then something like
grep -r 'class MyClass' *.php
I need to search a text file for a string of numbers which are different lengths, and always are between number=" and " like:
number="1234567890"
number="22390"
I need to grab those numbers and pipe each one to a line in a file. I've already tried something with awk and that didn't seem to work.
I have a file:
979798707
787862348
766428634
I want to see if all the records in the file are present in the contents of the files of a particular directory.
Basically I want to say if grep doesn't return anything, then report.
For example in /tmp dir I have 4 files and flast 2 values (787862348 and 766428634) are present in the files of /tmp dir, but first one (979798707) is not. I want to echo that in a reporting file.
something like:
while read line
do
# if ! grep -rl $line /tmp
echo $line >> are_not_present
done < "myFile"
How do I achieve " if ! grep -rl $line /tmp"? That is, if the line is found by grep, then grep will print the output, but if grep does'nt find it, it will print nothing. How can I check if grep didn't find it (i.e. printed nothing)?
I have ASCII files to parse that 48 hours old or more ; I can identify them like so
Code:
find . -name "FILE*TXT" -mtime +1 -exec ls -ltas '{}' ';'
Some files have a list of hardware errors (we test electronic components), some have none. If the file name has no errors, I still want to display a message like so
Code:
grep ^err R*VER && echo "No error"
FILEA.TXT:err->USB3910err
FILED.TXT:err No Error
This grep statement works but it seemingly overrides the find() statement above if I run both at the same time... How can I combine the two statements to create a report that lists the filename and error(s) like so
Code:
FILEA.TXT Button3320err
FILEB.TXT USB3235err
FILEC.TXT IR Remote2436err
FILED.TXT No error
Is it possible to return "No error" with the file name without error?

How can i use grep (or any other command) to check for lines that begin with N number.
E.g. I want to print out commands (from history), but only from the command number 50 until #200.
This one doesn't work:

history | grep "^[50-200]"
Should print out something like:

Q: Is there any way to use grep and sed with a string variable rather than with a file?
The problem: Im running through a LARGE (about 10,000 lines) xhtml file and need to replace every instance of lines beginning <p>~
The following code works but takes a long time mainlly because an in/out operation needs to be carried out on each line. If I could read from a string rather than a file it would take a much shorter time!
Code:
#!/bin/bash
count=$((0))

echo "waiting....."

I am using Sun 5.9.
I am putting the value "Feb 10" in variable 'c' here.
Code:
-bash-3.00$ c=`date | awk '{print $2 " " $3}'`
-bash-3.00$ echo $c
Feb 10
But when I am grep-ing value of 'c', I am getting this error.
Code:
-bash-3.00$ ls -lrth | grep $c
grep: can't open 10
This is because there is a space between "Feb" and "10".
I know you can use grep to find keywords in filenames, but is there a variation that can enable you to search the content of the files themselves?

I am using grep to filter out directories I am not interested in like this:svn stat | grep -v data/charts | grep -v lib/model | grep -v web/picsIt seems a bit "hacky". Is there a better way to specify more than one string to ignore, so that I dont have to chain multiple grep commands?

I have done a bunch of searches on this but the terms seem to get tangled in the more popular search of "colouring the output of grep / awk". I am trying to find a way to grep/awk through the output of a command to find text of a specific colour. The command's output has a range of colours signifying too many different things to specify using text, with colour being the only form of grouping.
View 5 Replies View RelatedI need to search for the following pattern with GREP in a text file:
So I tried already:
But none of those works...I think probably because GREP doens't like the special character > in the middle of the serach pattern.
At the end I just need to now if GREP found the pattern in the file or not, so it should give me a 0 or a 1 back, once I check the value of the variable "?" after using the grep command.
I want to pipe the output of a command into grep as the search TERM, rather than the text to be searched, like this for example

I am having trouble using grep command. I want to search for each line in first file in second file and if they are present, write to file called successfile else to failfile. Below is the code

Can anyone please tell me what I am doing wrong? code...
somewhere lurking is a file containing the default print resolution, which is not being overwritten by printer settings or cups management. I've asked on the cup forum and nothing successful.
So here's the question:
How can I configure grep to search recursively through all files in a directory, or if need be starting from root to find the pattern "2880" I've looked in the man page for grep and I can't see how to do it, is grep the right tool to use for this ?
I know grep can search recursively (ie through all subdirectories to the bottom of the directory tree), but is it possible to ask grep to only search say, 3 levels down? That means the current directory, any directories in the current directory, and within any directories within those?
