Programming :: Bash Function For Searching Files ?
Jun 15, 2011
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 `}'"
...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.
I looked on the net for such function or example and didin't find anything, thus after having made one i guess it would be legitimate to drop it to see what others thinks of it.
#!/bin/bash addelementtoarray() { local arrayname=$1
(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:
*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.
Code: #!/bin/sh #System commands and other configurable. IPT=/sbin/iptables IP6T=/sbin/ip6tables IPST=/usr/sbin/ipset MODP=/sbin/modprobe GET=/usr/bin/wget INT_NET=192.168.1.0/24 .....
I can find lots of tutorials in how to use if, then, else. However, how do I define a variable inside the function? SEE>> Code: for c in $ISO Also, am I using the 'test' command correctly( -/+ week as valid test)?
I have a file that contains 5 fields and anothen one with two I want to take the value from user and search file1 and if the value exists then write in file2 to the $2 to the line that $1=value
I was wondering if possible in bash for a variable to take the value of a function, I mean the function returns a value and a variable will take it. example:
I found a weather function for bash from searching google, and started to finesse it. This is what I have so far, any tips to finesse it even more?
Code: # Based on code by Crouse at www.bashscripts.org weather() { declare -a WEATHERARRAY WEATHERARRAY=('lynx -dump "[URL]?hl=en&lr=&client=firefox-a&rls=org.mozilla%3Aen-US%3Aofficial&q=weather+${1}&btnG=Search" | grep -A 18 -m 1 "Current:" | sed -e 's/^[ ]*//' | cut -d '|' -f 1-5 ') echo Weather for the zipcode of $1:$' ' ${WEATHERARRAY[@] } }
I've got a problem with a piece of code. Basically, I use my listRegularFiles function in two separate places in my code. The first time I run itit appears to work perfectly well. If I use it a second time, however, it blows a gasket. I'll post my code below, and if anybody has any ideas,Here's the code for listRegularFiles:
I need to rename the resulted searched files from a loopI have the following code:
find . -name DOC* | while read i do find $i -type f -name '*.txt' done
basically, I am searching for all txt files inside any folder starting with DOC name.this code is working fine with me.I need to rename those .txt files to .txtOLDOS: Ubuntu 10.4Bash shell
I am doing some Linux kernel programming for my research project. I need to record the timestamp (by using cpuid and rdtsc) when an interrupt handler (top half) is first invoked. Due to the time critical nature of the problem itself, I have to do the timestamping inside the interrupt handler itself (the first operation when the handler is called). However, I understand that tasks that are not so time critical should be deferred to a tasklet function (bottom half) for processing because other interrupts are disabled in a (top-half) interrupt handler. I am currently out of idea on how I can pass the timestamp information that I have obtained in the interrupt handler to the corresponding tasklet function.
I am an uploader to a various hosts, so this tiny script me a lot. I make a rar archive and split files with 100mb. I could get 3-4 or even 76 parts of rar files and it would take me some time to paste all these urls to remote upload function of filehosting sites. For example:
Code:
server:/home/cober/downloads/teevee# ls -al total 358784 drwxrwxrwx 2 root root 4096 Dec 8 19:38 .
I did searched you tube but my results were not great.I have 2 books on KernelProgramming.I feel I need if some where I can get a video tutorial which can help me to understand how to develop a Linux Device driver that will be great.I had a look at Greg Kroah Hartmans video lecture of developing patches on ......I have been reading books and a lot of stuff.So I wish if I could get a video lecture that would be better
What I want to do is to create a script that will interpret the following string and save into variables part of its name
m02_+1+7_London_0000$01.cfg as ------X-Y--City--------- X=1 Y=7 City=London
[code]....
then I want to copy the files that go all the files with the same City and X and Y to the same subfolder City/MX.Y I will need some help start doing that. And I think the first would be to get part of the filenames strings into variables.
I am trying to find a nightly backup if it was successfully copied over, rename it and curl, but it's always passing the check even if the file is older than specified. From the command line it does as it should. Example is here;
Code: find /backup -type f -mmin +4440 -exec echo "found" {} ; - nothing returned (good). Then I change the time
I'm trying to rename a lot of files getting rid of the space on the names. For that purpose I wrote this very simple bash script, but for some reason is not working.
Code: for i in "$(ls)" do j=$(echo "$i" | sed 's/ /_/g') mv "$i" "$j"
done But what I get in return for each line is just one long file name with all the file names concatenated. I've tried with echo -e "$i" as well with no results. This has to be something really simple that I'm missing but I just can't see it.
I am trying to write a simple script to list all the files in a directory. The script I wrote was as below where the pdb_files is a directory and all the files which I want to list are in that folder.
Code: files=`ls -F pdb_files/*THERMO*` for inFiles in $files do echo $inFiles
I need to fgrep a list of things which are in a file. The file in which I will do the SEACHING is a large text file and I need fgrep to output each item from the list as a file with the item from the list as the file name.
I have around 600 empty text files that I need to add the name of this file as part of the data, I meanfiles from "file1.txt to "file599.txt, all of them empty, and I need to get the name inside the file, so, when I open the file show the name as part the data "file1".these files were created on my web site, I am thinking in a small script in bash
How can I iterate over all the files in the current directory to check for certain permissions? This is what I have:
Code: #!/bin/bash for file in *.tar.gz do if [ -r "$file" ] then echo "$file is readable" else echo "$file is NOT readable" fi done
But this only checks that the current user has read permissions for each file. I want to check that the group "others" has read permissions for each file. How can I do this? Is there a built in function to check if a file has read permissions for the "others" group? Otherwise, I thought I might be able to use this: Code: $ stat --format=%a file 744 And parse the output "744" and make sure the 3rd number is between 4 and 7 (since the octals 4-7 have read permissions for others).
I'm building my first BASH programs and I have a hard time. I can't do a search in a folder and filter only script files without extension, the problem is to differentiate the script files from the others. I tried with ls I tried with find and i don't find a way to make it work.
I have about 50 files that the script will operate on, they are all located in the same directory.I need a bash script that will operate on all files in a directory. The script needs to add two lines to the beginning of each file based on the file name, and one line to the end of the file.A file named myfile.h should add these two lines to beginning of the file:
I have wrote a 1 line command that parses a file, locates the IP Address in the file and then trims the output the way I want it, and then sorts numerically and by uniqueness and then >> appends to output.txt
I can get all the IP's into 1 file "output.txt", but what I am really looking for is some type of way to create a text file, for each IP it finds labeled xxx.xxx.xxx.xxx.txt and also put that ip address into that file..
