Programming :: How To Get Grep Output 0 - 1 And Test It
Apr 7, 2009I am trying to use a shell script to find a string in a file and do something when found. code...
What should happen is pppd will start in a different process and stream it's output to pppdout. pppdout should be created in the current folder. Then the script should periodically check the pppdout file for the string Script (which eventually will appear, some seconds later) and when found exit the script. Ultimately the script will do something useful when the text is found. However, the output from the program is a repeating: 'scriptname.sh: 12: FOUND: not found'
Where scriptname.sh would be the name of your script and 12 refers to the line with 'done'.
Why does grep not find the text, or at least why deos my script not check the grep output correctly?
Programming :: Omit Specified Characters From The Output Of A Command?

Programming :: Remove Characters From Within Variable
Feb 20, 2011I am doing a mysql query with a bash shell script like:
mysql translator -u root --password=******** -e "SELECT word FROM tagalog ORDER BY RAND() LIMIT 1" | while read line; do
echo $line
So when I echo the value of $line I get:
word
magandang umaga
"word" is the name of the row in the table and maganda umaga is a randomly selected choice from the row. Is there a way i can remove the name of the row from the variable $line. With a result that will allow me to echo $line and output only the randomly selected entry in from the row e.g. magandang umaga

Apr 27, 2010I hope you can help. I have a collection of spreadsheets with data that needs to be imported in to SQL. The data has been manually entered although there are portions where data has been copied and pasted from the web.
When converting these sheets to a CSV I get strange characters where it looks as though data has been copied and pasted. Is it possible to write a script (AWK?) to pull out these characters?
I guess the script will need to keep alpha characters, spaces, numerics and commas but nothing else. How easy is this to do?
Programming :: Storing Grep Output To Feed Awk To Retrieve Entire Records Matching Variable
Jul 28, 2010I have two files :
FileA
prot1
prot5
prot9
prot15
[Code]....
What I need to do is to extract from fileB the fields containing only the strings in fileA.
I thought awk could do the job easily with :
Code:
awk 'BEGIN { RS = "###" } /'$variable'/' fileB > output
where variable would maybe be the output of grep from fileA. So can I store the output of grep in a variable to use it afterwards with awk ?
something like that:
Code:
result=`grep prot. fileA` ; awk 'BEGIN { RS = "###" } /'$result'/' fileB > output
but that doesn't work. I'm always getting the entire fileB.
The output of grep get stored in the variable, I verified that with echo. So there is something that I just don't get... It seems to me that the above line should work.
Programming :: Remove All Alphabetic Characters At Beginning Of String
Jul 26, 2010I am working with a Tcl script and have some strings in the following format (RE):
[a-zA-Z]+[0-9]{6}-[0-9]
There are some leading letters, combinations of capital and lowercase. Then six digits, followed by a hyphen, then one more digit. I would like to remove all of the leading alphabetic characters from the string. The resulting string would then be in this format: [0-9]{6}-[0-9]. In other words, six numeric digits, a hyphen, then one more digit.
I have tried:
Code:
set newstr [string trimleft $origstr alpha]
But that only removes the first alphabetic character, not all of them.
I couldn't get anything with regsub to work correctly, but I am somewhat of a noob with RE's in general and regsub in particular. There are usually 5 leading letters at the beginning of these strings, and I could in most cases get away with using string replace and constant indices to extract the substring. However, my preference is for this to be robust enough to handle all cases with 1 through n leading alphabetic characters.

General :: GREP - Search Special Characters
Feb 10, 2010I 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.

General :: Bash - Using Find Or Grep To Locate Filenames With Accented Characters From A Different Encoding System (Windows)
Dec 6, 2010I tried to tag late onto a question similar to mine on stackoverflow (Find Non-UTF8 Filenames on Linux File System) to elicit further replies, with no luck so far, so here goes again... I have the same problem as the OP in the link above and convmv is a great tool to fix one's own filesystem. My question is therefore academic, but I find it unsatisfactory (in fact I can't believe) that 'find' is not able to find non standard ascii characters.
Is there anyone out there that would know what combination of options to use to find filenames that contain non standard characters on what seems to be a unicode FS, in my case the characters seem to be 8bits extended ascii rather than unicode, the files come from a Windows machine (iso-8859-1) and I regularly need to fetch them. I'd love to see how find and/or grep can do the same as convmv.

If I am not using grep command my script would be as
find $directory -type f -mtime +7 -exec remove.sh {}\;;

General :: Grep - Filtering Output By OR Condition
Aug 13, 2010Is there some way to filter output of command by OR condition in Linux? There is filtering by AND condition with grep in way like:
ls -l | grep "^a" | grep "z$"
That says: list all files that beggins with "a" AND ends with "z" (so there is shorter way to write this: grep "^a.*z$", but it is not matter). Is there some way to perform test by OR condition? For example: files that starts exactly with "xen" OR files that ends exactly with ".rpm". But exactly, not something like:
grep "[xen]{0,3}.*[.rpm]{0,4}"

General :: Filtering Out Duplicate Lines From A Find/grep Output
Mar 22, 2010I have some big files of logs that contain errors printed by an app. They are most of the time relevant, however most of them are similar. So i figured i could check what happened between a time interval with a find.
Im using this one

And I get an output similar to this one.
Code:
Is there a way to condensate the output lines to get only one or two, indicating the start and last occurrence of a block? Or I need to create a program to do so?
Because right now I get thousands of similar lines, but when I'm scrolling through them i sometimes miss relevant information that i would've otherwise noted if it wasn't all that spammy.
