Programming :: Can't Seem To Find Scripting Tutorials
Dec 1, 2010I am familiar with C, C++, and Python at a novice level. I have recently tried learning bash, but I can't seem to wrap my head around it. My biggest problem, I think, is the huge "vocabulary"-- it seems like there are thousands of commonly used commands, and several ways to use said commands.I've done some google searches but can't seem to find scripting tutorials that tailor to n00bs. Most go from basic "Hello World" programs to very complex scripts.

Programming :: Bash Function For Searching Files ?
Jun 15, 2011I'm making a small script for searching and doing some operations with photos, but I'm kinda stuck on this little function:
Code:
function findallformat {
prefix=""
if [ $1 = -pre ] then
[code]....
That function should find for every file with a certain type; and you can specify a prefix using a "-pre" followed by the prefix that you want to search. The format should be "stackable", so you can use as many types that you want, without repeating the same function on the code.
Example: findallformat -pre IMG_ .JPG .CR2 #That should search files that start with "IMG_" and finishes with .JPG and .CR2. My problem it's that, when I try to use it on the script, it says "bash: syntax error near `token' unexpected `}'"
Programming :: Grep Searching For Strings With (apostrophe)
Nov 10, 2010I am trying a search for a pattern in the file. I can have any character in the pattern. I am pretty sure I will have $, ", ', ^, ` etc., The Problem I am facing is if I use "" (double quotes) to enclose the pattern, it gives special meaning to $, ^ and " within the string. I have no control over the pattern input. I am getting it from some other file. On the other hand, If I use '' (single quotes) to enclose the pattern, it gives special meaning to the ' (apostrophe) within the string and terminates the pattern prematurely. How do I disable the special meaning these characters have? For example, in perl, I could enclose the pattern within Q and E. Is there an equivalent in grep pattern expression? I could find one in the man page of grep. Is there a solution to this problem?
View 5 Replies View RelatedProgramming :: Searching Recursively By Exif Date?
Feb 20, 2010I have searched diligently but can't seem to find a way to search by exif date. Most of my searches turned up commands to manipulate EXIF data not just search by it. I have found some likely tools but suspect that I don't know enough bash to recursively find a .jpg file by it's exif date. For example, exiprobe and exifgrep look promising (see examples below).
I have made some progress. At first, I couldn't associate the file name with the date given but learned that the "n" option forces each output line to start with the file name. Now, I need to make the command recurse but can't seem to manage it.

Programming :: Bash - Searching Strings For Array Elements?
Apr 30, 2010...and returning the index of the found element in its array.
I have:
for ((i=0; i < ${#array1[@]}; i++)); do
# Read each line of the file test
if [[ $(eval "sed -n '$(($i+1))'p test") == *${array2[0]}* ]]
stuff
I want to find the index of the found substring in array2 and only if it isn't found, move on to the next element of array2. I don't know the size of array2 so that [0] has just got to go.
Programming :: Script For Searching Through Messages For Multiple FTP Hits
Oct 25, 2010My script looks really crap and messy, the logic isn't great and I'm not hugely happy with it. Also it echo's $i instead of an actual IP address (line 10). How to improve this. It basically searches through /var/log/messages for multiple FTP hits and when the hit count is higher than a specific number the IP is added to a config file and ftp is restarted. There are some obvious flaws in my script.
Code:
MAXHITS=0
TOPHITS=`grep "FTP session closed." /var/log/messages* | awk '{print $7}' | sed -e 's/^.*[//' -e 's/].*$//' | uniq -c | sort -nr`
HITNUMB=`echo $TOPHITS | awk '{print $1}'`
IPHIT=`echo $TOPHITS | awk '{print$2}'`
HIGHIP=`echo $TOPHITS | grep $HITNUMB | grep $IPHIT | awk '{print $2}'`
if [ $HITNUMB -gt $MAXHITS ]; then
for i in $HIGHIP;
do
echo $i
sed -i '78s/$/,$i/' /opt/etc/proftpd.conf
/root/ftp restart
done
else
echo "not greater than $MAXHITS"
fi
I'm not even sure what will happen if I get multiple responses for my $TOPHITS. It would be cool if it could search for IP's already blacklisted somehow, it might actually be easier to just create a file with a set of blacklisted IP's or something.

Programming :: Searching Thunderbird Emails & Extracting Information
Jun 8, 2010I have a load of emails in my Thunderbird trash folder and some of them (all with a similar subject) I want to extract the email address for them and put in a text file. I have located the trash file but it seems that it is just a big flat file with a concatenation of all my emails in it, varying number of header lines etc etc - ie, something which really doesn't seem to suit awk, sed, grep etc.Does anyone know of any way this might be accomplished, or any third party tools which may help?

It is failing to give the output. IF I run the find command on the console the I am getting the correct file name with location

Debian Programming :: Searching For A List Of Strings In File With Python
Oct 14, 2013I'm trying to search for several strings, which I have in a .txt file line by line, on another file.
So the idea is, take input.txt and search for each line in that file in another file, let's call it rules.txt.
So far, I've been able to do this, to search for individual strings:
Code: Select allimport re
shakes = open("output.csv", "r")
for line in shakes:
if re.match("STRING", line):
print line,
How can I change this to input the strings to be searched from another file?
So far I haven't been able to.
Programming :: Sed Script - Searching For Text Within File / Replace With Variable
Feb 25, 2011Code:
#!/bin/bash
VARR=`cat /proc/asound/cards | grep HDMI | cut -c 1-2`
VARX="defaults.ctl.card $VARR"
VARY="defaults.pcm.card $VARR"
FILE1="alsa"
FILE2="alsa.new"
echo $VARX
echo $VARY
sed "s/defaults.ctl.card*/'$VARX'/g" $FILE1 > $FILE2
This is what I have right now. Well, I thought I knew sed, and apparently I don't... I tried writing this for someone else, and this has given me trouble, so since the user pretty much figured it out on his own, here it goes.
Say VARR=1, so VARX and VARY contain the above text, appended by 1.
What I am trying to do is replace the text "defaults.ctl.card 0" by VARX and "defaults.pcm.card 0" by VARY. The contents of FILE1 is the file being used to search for both text fields, and FILE2 is the output file. I tried using single quotes, double quotes, and a mixture of both, and no go whatsoever. So my question... What is the proper way of searching for text within a file and replacing with a variable?
Programming :: Bash : Searching For Info And Changing The Color Of Keywords In The Results?
May 5, 2011(bare with me as I am sort of new with scripting) I am trying to figure out how to run a script that does a basic chkconfig and to get only those services that are running, but changing the color of "on" to red in my output file. Here is what I am working with so far:
Quote:
#/bin/bash
RED=$(tput setaf 1)
BLK=$(tput setaf 0)
[code]....
*I had to substitute a "-" and <colon_symbol> for ":" in front of the on's, because the forum thought they were smiley faces (i.e. n) how to make the "on" to be red while the rest of everything remains in black text. I have been trying to read up on sed and awk, but it is still pretty much a mystery to me right now. There will be other things in the output file that I wouldn't want a rogue "on" to be in red, so just the instances of "on" in that one chkconfig return.
General :: Any Good Tutorials Out There For Sed And Awk?
Feb 8, 2010I plan to design a general framework for structural optimization.I already have a pre-processor module that I can call in batch mode, a Finite Elements Solver, and a heuristic non gradient based optimizer that can process the outputs of the solver, so as to adjust some input variables in the pre-processing phase ( geometry and topological definitions of my structure ).
I would like to parse the huge ammout of data that is released by the solver ( an ascii text file) to filter out some reauired results in some specific points ( maximum allowable deflections or stresses within my structure ) since it is this infoemation that will be fed to the optimizer engine so as to feedback on the quality of the changes made in the topological definition.The only way to do this in batch mode is with awk, or with sed..
