How do I find a string in files in a directory. And these file names begin with letter a. I also want to get the number of occurrences of this string from the grep I run.
I tried this:
cat * | grep -c string but it searches all files. I just want to search files that begin with letter a

View 13 Replies View RelatedI 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:
Code:
C:u002Cdatau002CDocuments
If I used:
Code:
sed 's/u0052//'
It only removes the first occurrence. How can I remove all occurrence in the line?

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))

How to grep a string like "ab?c12345678" where 3rd character is unknown, while other characters are known.
View 2 Replies View RelatedI 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".

The line to be searched looks like as below. "Output Rows [1], Affected Rows [1], Applied Rows [1], Rejected Rows [0]"
Here I have to search whether the affected rows is 0. But the code below picks up other values also (lie 10, 20.. etc). How do we write to get an exact match for 0? Code: affected=`echo ${line} | cut -f6 -d" " `
affectedcount='echo ${affected} |grep 0 ` 2) Also, I need to check whether the rejected rows > 0
Code: rejected=`echo ${line} | cut -f12 -d" " `
rejectedcount='echo {rejected} |grep [1-9]`
