I'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 `}'"
I 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 13 Replies View RelatedI 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.

...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.
My 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.
Suppose i have a file(1.txt) separated by TAB delimiter in a line

I 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?

I have around 100+ files name with some particular extension , this code works fine if the directory name does not have any special character in it like " "(white character) .
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
/home/user1/public_html/mediawiki/config/movie.mp3
/home/user1/public_html/mediawiki/movie.mp3
/home/user1/public_html/mediawiki/pop.mp3
/home/user2/public_html/index test/pop.mp3
/home/user2/public_html/index test/web.xml
/home/user2/public_html/song.mp3
If I echo the file name from the script Then output is little missed match when a directory name has special char like " "
/home/user1/public_html/mediawiki/config/movie.mp3

I am not sure what is wrong with script or my code .. Does shell have un-controlled behavior of manipulating the output of any command.
I'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.
Code:
#!/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 > $FILE2
This is what I have right now. Well, I thought I knew sed, and apparently I don't... I tried writing this for someone else, and this has given me trouble, so since the user pretty much figured it out on his own, here it goes.
Say VARR=1, so VARX and VARY contain the above text, appended by 1.
What I am trying to do is replace the text "defaults.ctl.card 0" by VARX and "defaults.pcm.card 0" by VARY. The contents of FILE1 is the file being used to search for both text fields, and FILE2 is the output file. I tried using single quotes, double quotes, and a mixture of both, and no go whatsoever. So my question... What is the proper way of searching for text within a file and replacing with a variable?
(bare with me as I am sort of new with scripting) I am trying to figure out how to run a script that does a basic chkconfig and to get only those services that are running, but changing the color of "on" to red in my output file. Here is what I am working with so far:
Quote:
#/bin/bash
RED=$(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.
I'm trying to get my program to go through the string typed in by the user and strip it of EVERYTHING but the numbers. I can't place my finger on what I'm missing.
Code:
Code: #include<iostream>
#include<string>
using namespace std ;
int main()

View 3 Replies View RelatedCurrently, I'm working on personal project. and I'm kinda stuck. What I want to do is that open a file, and edit that file (deleting unwanted characters). The problem arises after I deleted unwanted characters, the file still has the same length of the original one. Let's assume that we have a file with "1234" in it. I deleted "3" ( I overwrite "\0" ) so now when I check the file, it's 124. But when I check the length, the both have the same size as 4
Here is an example source code
int length, length2;
num = open("a.dat", 2)
length = lseek(num, 0, 2); // Initial length
lseek(num, 2, 0); // editing
write(num, "\0", 1);
length2 = lseek(num, 0, 2); // Final length
close(num);
When I print those values those are exactly the same. Length2 should be one less than length, but the both are 4. What's wrong in m code? Am I supposed to use different character rather than "\0"?
I have a file which contains milion of records. It contains 12 columns seperated by "||" (delimeter).
First two fields contain first name and last name of a person. Now my requirement is to delete all those records from this file for which:
First two fields does not contain any alphabet.
For e.g i have below mentioned records in file:
gaurav||gandhi||123||456||789
#a%bcd||123abc||89|90||91
12345||@@@||89||123||234
***||!!!!||98||76||90
Now, last two lines should be removed from this file since first two fields does not contain any alphabet for these two records.
I have a very, very large log file (360MB) that I'm trying to thin out. As it turns out the majority of this file has entries that aren't necessary so I'm attempting to build a command that will strip these out. The following command works to display only the data that I do not want:
Code:
cat xml_results.log | grep -B 6 -A 5 "YYY ZZZ"
This displays exactly the data I want to delete from the file by displaying the expression and six lines above it and five lines below it. However I'm at a loss as to how to remove this data from the output and display everything else. I looked into the -v option with grep redirecting the output to a new file:
Code:
cat xml_results.log | grep -B 6 -A 5 -v "YYY ZZZ" > xml_filtered_results.log
However it doesn't work, the new file is the same size as the old one. What am I doing wrong? Is there a better method of doing this? I'm a bit out of my element since the method I'd normally use can't handle files of this size.

I've tried a number of suggestions found on the internet and none of them work. Here's one:Code:mv "$x" ~/.Trash/...where $x is the pathname of the file passed to the script.I've also tried different paths to Trash - on Desktop, in Home folder, in my user folder, it makes no difference. Either nothing happens, or more often, the file is simply copied to my desktop or userfolder with the name "Trash".What is the actual path to the Trash folder and how can I move files there?

are there any commands to search your Mac using terminal? I tried usin grep to search but it seems somewhat unresponsive and nothing comes up.
For example, I would type "grep Files" (A folder name) and it just prints a blank line and nothing happens.
