Programming :: Echo Hello Command Does Not Return
Jan 11, 2010I am testing the serial ports on a Single Board Computer(SBC) running Linux kernel 2.6.29. I usually do this by connecting the serial port to another PC serial port, then doing "cat /dev/ttyS0" on PC and "echo hello > /dev/ttyS0" on the SBC. However in the current system, "echo hello > /dev/ttyS0" command does not return at all! Also no characters appear on the destination port. I am running the echo command as root. The system boot messages show that the serial port in indeed /dev/ttyS0.

Jul 21, 2010I'm creating a usb device driver that needs to be able to read from two different endpoints. I couldn't see any way of having two read functions in the driver, so I got round this by reading from one of the endpoints with read, and the other with ioctl.However this hasn't worked, the ioctl call from c returns -1. I added a printk command in the driver in the ioctl function, however looking at kern.log I can see that this function is never being called. Does anyone have any ideas as to what the problem called be, or a better method of being able to read from two different endpoints?

Feb 14, 2011I wanted to find and replace a string from a perl file. I have written a script in bash which runs the following command.
perl -pi -e "s/$findstring/$replacestring/" testfile
where as $findstring = print F_WC_TMP"$line
";
and $replaceString = $line = join ' ', split ' ', $line; print F_WC_TMP"$line
";
But when I am running the above command, i think it is replacing the $findstring with the above mentioned string and hence it contains a $line, it is looking for the variable $line and not finding the exact string. I am confused about how to search for a string that contains $ in it and replace it with another $string.

View 1 Replies View RelatedProgramming :: BASH Read File Once Then Return To Top?
Aug 8, 2010I have a script that reads part of a line, delimited between the first and second intended part by a colon. Then it "chops" the part after the colon, which are words offset by commas (counting them beforehand so as to catch every word in the string's second part), like this:
Code:
"COLORS.JPG:red,orange,yellow,green,"
(Returning)
red
[code]....
single script that parses/breaks both parts of a line like this "COLORS.JPG:red,orange,yellow,green;blue,indigo,violet," so that the two parts, separated into single words (or two and three words, sometimes with spaces) can be used as single-line annotations and written to JPEG files using Exiv2. So far, I haven't been able to come up with a script that does this without one part of the total string(usually that part after the colon) becoming the first word in the second array. In other words, I look for this:
KEYWORDS:
[ ]red
[ ]orange
[ ]yellow
[code]....
Or vice-versa (ie, the second array winds up as a single-line "member" of the first). I think it's because I'm using a single while read loop to read the text file in which the filenames and substrings happen to be. If there's some way of reading a file once and going back to the beginning to read it again in another while loop, I haven't found it.
Programming :: BASH: While True To "read" A File?
Sep 16, 2010I had a script once that had in it a while true; do and read lines or data from a file similarly to a while read; do. I have a script I'm working on now where I'm trying to "prove the negative" that certain substrings culled from one file do not appear in another file. I'll try to explain what I mean with an example. An item in one list might be
Code:
[URL]
But the other list may only have
Code:
harvey1996nicks:Six stores in north London
harvey1997nicks:Three stores in Bristol
harvey1999nicks:Eight stores in the lower Midlands
The problem is, other items in the first list do match items in the second. The script I'm drawing this from has already pulled those out and written them to one (or several) lists that I've been able to use with other programs (Exiv2 specifically). The furthest I've bothered to go in the direction of "proving the negative" is a slow "if/then/fi" loop that looks like this:
Code:
linecheck=$[linecheck+1]
if [[ "$linecheck" == "$axe" ]] && [[ "$matchX" == "" ]]; then echo -e $file>>nomatches.txt; fi
linecheck is counting the lines of the second file -- the one with the designations or "labels" (the "so many stores in ..." from my example) -- as they are checked against the file names in the first (the "harvey199*nicks.jpg" etc of my example. axe is the number of lines in that first list (culled from a cat |wc -l at the beginning of the script). matchX is the variable the "prove the positive" script used for matches, one list to the other, which then got written line by line to a text file.
Programming :: Find Command With Standard Error Output And Mail Error File
Nov 11, 2010We make everyday a DB Mysql backup on Linux redhat Enterprise. We are using a bash shell script (and putting it in the crontab) to execute it automatically everyday. We added a line to this script telling, once the backup has completed, to find old backup files (stored on hard disk after each backup) older than x days to remove them. We use the find command (search for file type) with the mtime option and in combination with rm command. Everything runs ok but we also want to add some new code to the same line: If find command cannot find anything or fails, for example if it cannot delete file or fails, send the error message (standard error output) to an error file (like error000001 and increasing) and mail the errorxxxx file to an email address for example to admin@companyname.com. What would be the code for this issue to add it to our find command in the same bash shell script??

Fedora :: Defined Aliases In File Not Working - No Command Found
Apr 15, 2011Defining tcsh aliases through a .aliases file has worked perfectly for me for years and years using cygwin and older versions of mandriva. I am encountering very annoying and mysterious problems when attempting to do the same thing with a .aliases file in a fedora 64-bit VM. Strangely, if I define aliases in the file, they won't work, but if I do so on the command line, then they will.
Here's a simple example: Suppose I define an alias for "ls" in the file:
alias ls '/bin/ls'
Then source the file. This happens:
me: ls : Command not found.
me: alias ls
/bin/ls
me: /bin/ls
file1 file2 file3 etc.
me: unalias ls
me: ls
file1 file2 file3 etc.
me: alias ls '/bin/ls'
me: ls
file1 file2 file3 etc.
A second example: if I place either of these lines in my .aliases file:
alias d '/bin/ls -alF !:1'
alias d '/bin/ls -alF !*'and source the alias file, this happens:/ me: d
Bad ! arg selector. However, if I define the alias on the command line:
/ me: alias d '/bin/ls -alF !*'then the alias behaves correctly:/ me: dtotal 376

The only thing I know is that I have the Iso image installed ... which is my linux distro .
