Programming :: Bash - Renaming Files Won't Work
Apr 1, 2010
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 have this cool bash script that I worked hard on. But it broke down when it can across files that had non-English characters. Another small problem was getting it to descend into a directory. If it renamed a directory it would not descend into that dir to rename the other files. I would have to run the script twice on the same directory.
Here is the script:
Code:
find -type d -o -regextype egrep -iregex '(.*.ogg|.*.mp3|.*.wav)' | while read s
do
rename -v 'y/A-Z/a-z/' "$s"
done
find -type d -o -regextype egrep -iregex '(.*.ogg|.*.mp3|.*.wav)' | while read n
do
rename -v 's/ /_/g' "$n"
done
A French name like this:
Code:
Chateau De Sable (imagine accents above the letter a)
became this:
Code:
ch303242tea_de_sable
This is not what I wanted.
Why would the script not descend into a directory after it was renamed?

I'm trying to rename ~11000 files. What has happened is I have files in the following format:
string1_100_string2_200_string3_300.log
now the numbers 200 and 300 are sometimes below 100 and the file looks like this:
string1_100_string2_99_string3_99.log
and I want to rename such files to be like this:
string1_100_string2_099_string3_099.log
I wrote a small matlab script but it seems to take forever so thought I'd try and do it bash and have got near to nowhere....

I have a bunch of files that I need to rename, ordinarily this is pretty easy task. The problem here is that the file names have Chinese / Japanese characters. ie [$$$$$$$$].SOMETHING BLAH BLAH.ext Where all the "$$$$" are insert Chinese characters. The problem is that sed or perl doesn't seem to handle the Chinese characters correctly so using a regular expression like this 's/^[*.]//' which would normally work doesn't. From what I have read so far I believe these characters are double encoded UTF-8 (not 100% sure) which could be the problem. So far I've tried numerous different regex's as well as playing around with convmv to see if I could convert the filenames to just single encoded characters but I've had no luck.

Is there a way I can do a "deep" renaming of files? For example, I can do this: rename 's/.JPG$/.jpg/' *.JPG to rename all files ending with ".JPG" to ".jpg", but this only works in the current directory. How can I make this recursive? There's not a flag (that I can see) that does this. Basically, I want to rename ALL files on my hard drive with an upper case JPG extention to make them have a lower case jpg extention.

I've been trying (and trying...) to write this script. I'm a complete newbie on bash scripting. This is what I've come up so far:
Code:
./reading
| Number of characters 48
| + Current: 107_david_guetta_-_missing_you_(feat._novel).mp3
| + Changed: 107_david_guetta-missing_you_(ft._novel).mp3
| + Matched: "(feat._" substitute "(ft._"
| + Morping: "107_david_guetta-missing_you_(feat._novel).mp3" to "107_david_guetta-missing_you_(ft._novel).mp3"

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

I'm currently learning bash programming and am trying to create a program to maintain a list of people. Here is the code so far:
Code:
#!/bin/bash
# Namelist
clear
[code]....
As you can see, I attempted to build in a protective measure to prevent duplicate entries using "if grep -Fxq "$FN $LN" /home/andrea/namelist.txt", FN and LN being first name and last name as you can see in the first read operation. However, this fails to actually work. Demonstrations:
[URL]
It saves the details to the file rather than displaying the error message, or in other words, it doesnt check the file properly.

I have a lot of filenames (strings) following the same convention
m02_+1+7_London_0000$01.cfg
m02_+1+8_London_0000$01.cfg
m02_+1+8_London_0000$01.cfg
[code].....
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 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 want to catch some outputs in two different log files in bash, file simple.log and all.log So far, the script is started like this:
Code:
xterm -e "(./myscript.sh | tee -a simple.log) >& all.log"
What I want is:
- In simple.log, I want all the stdout but WITHOUT errors.
- In all.log I want BOTH stdout and stderr.
So all is ok, and the output becomes:
all.log
Code:
starting copying files
mv: cannot move ... : permission denied
copying completed
simple log
Code:
starting copying files
copying completed
But, in the new xterm, I'm loosing stdout. There is no output.How can I have the files logged as they are but also have the stdout in the xterm.

Have worked with Linux at home for some time and have wrote the below script.
This script is run when a .torrent file finishes downloading and extracts any .rar files into an extracted directory.
However there are 2 thing that i cannot for the life of me get working.
These are:
1. I need the script to check a txt file to see if the file has been extracted previously.
2. The script does not work with any paths that contain spaces.

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.

Never mind, I figured it out myself. Firstly, the old version of BASH I'm using doesn't support
Code:
for i in {1..27}
So I had to use
Code:
for i in 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27
Secondly, it was simply
Code:
#!/bin/bash
for i in 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27
do

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:
Code:
#ifndef MYFILE_H
#define MYFILE_H

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..
xxx.xxx.xxx.xxx = the ip address it finds

However, the ffmpeg command generates a temporary file blahblah.mpg.tmp of about 1GB per hour of transcoded video.My issue is that I can't seem to delete these files automatically from any bash script.Now from the command line, I can cd to the directory and just rm -f *.tmp and they get deleted. However, from my script, that same command doesn't remove those files. I thought maybe the file was in use, so I put a sleep command in for like an hour before the delete happens, but it still fails. I also put rm -f /mnt/mythtv/*.tmp in a root cronjob and it still doesn't delete the files.
If I just rm *.tmp I do get a prompt about "Are you sure you want to delete this write protected file?". But the -f switch seems to work fine as a normal user from the command line and just delete them.Does anyone have an idea how to troubleshoot this problem? The particular filesystem that the tmp files get generated on is on it's own xfs partition mounted as /mnt/mythtv.

I have to copy some log files with a cron job; I'd like to copy only the newer files added because I run the script with a weekly cron. all the log files are named like "10-03-29.CVS" and reside in a dir. When I copy I'd like to copy only the files not already copied with the last cron job.

*I'm using Ubuntu 10.10
My issue is I can't handle the files with spaces in their name, I've donde the below script to print each file found inside folder and subbfolders with "find".
I would like to "ls" to each file found with its complete path and with its basename too.
Code:
files=$(find . -type f)
for each in "$files"
do
ls -l "$each" # 1rst option I've tried to list with full path
ls -l "$(/bin/echo "$each")" # 2nd option I've tried to list with full path
ls -l "$(/bin/echo $(basename "$each"))" # 1nd option I've tried to list with it basename
[Code].....
How can I list "ls -l" in both cases (with full path and with basename) when there are files with spaces in their name?

Writing script to create backup of file by adding datetime to file name. Basically test for file presence if there, cp with datetime then rm original cp works fine from command line but get cannot stat `full path to file': No such file or directory
Code:
Here are the errors: cp: cannot stat `~/html/CVP_dadamail/.dada_files/.logs/errors.txt': No such file or directory rm: cannot remove `...': No such file or directory
The for statement is a placeholder as I have same file to backup out of several directories. using "bash -x scriptname" -OR- inserting echos, I can see I've constructed the strings properly. Believing it might be related to the hidden directories, I tried setting the shopt "glob" options to no avail.
Ultimately I'll add the other directories to the for loop and then run this from a cron job, so if you see potential pitfalls knowing I'm headed in that direction...believe construct would be

What's the command for renaming files? I thought it was "mv"--I typed "info" and read
Quote:
* mv: (coreutils)mv invocation. Rename files. So, desiring to give a .JPG extension to a jpeg file that had no extension (because I dug it out of my Firefox cache), I typed
Quote:
mv '/home/josh/Desktop/Natalie pictures/DEC8FFA5d01' *.jpg
That didn't rename the file; it made the file disappear from its folder. What did I do wrong?
