I'm looking for a script to copy and rename one single file in a folder 60 times with backward sequential day in OS X
For example diary.list becomes
20140320_diary.list
20140319_diary.list
20140318_diary.list
20140317_diary.list
20140316_diary.list
....
20140120_diary.list
I know this simple script to copy and rename with previous date to it
cp diary.list $(date -v -1d '+%Y%m%d')_diary.list
But how do I put -1d in a loop so that it repeats 60 times?
Thanks heaps!
for i in `seq 1 60`; do cp -v diary.list $(date -v -`echo $i`d '+%Y%m%d')_diary.list ; done
Omit -v from the cp command to quiet output.

I have a bucket in google cloud storage. I have a tmp folder in bucket. Thousands of files are being created each day in this directory. I want to delete files that are older than 1 day every night. I could not find an argument on gsutil for this job. I had to use a classic and simple shell script to do this. But the files are deleting very slowly.
I have 650K files accumulated in the folder. 540K of them must be deleted. But my own shell script worked for 1 day and only 34K files could be deleted.
The gsutil lifecycle feature is not able to do exactly what I want. He's cleaning the whole bucket. I just want to delete the files regularly at the bottom of certain folder.. At the same time I want to do deletion faster.
I'm open to your suggestions and your help. Can I do this with a single gsutil command? or a different method?
simple script I created for testing (I prepared to delete bulk files temporarily.)
## step 1 - I pull the files together with the date format and save them to the file list1.txt.
gsutil -m ls -la gs://mygooglecloudstorage/tmp/ | awk '{print $2,$3}' > /tmp/gsutil-tmp-files/list1.txt
## step 2 - I filter the information saved in the file list1.txt. Based on the current date, I save the old dated files to file list2.txt.
cat /tmp/gsutil-tmp-files/list1.txt | awk -F "T" '{print $1,$2,$3}' | awk '{print $1,$3}' | awk -F "#" '{print $1}' |grep -v `date +%F` |sort -bnr > /tmp/gsutil-tmp-files/list2.txt
## step 3 - After the above process, I add the gsutil delete command to the first line and convert it into a shell script.
cat /tmp/gsutil-tmp-files/list2.txt | awk '{$1 = "/root/google-cloud-sdk/bin/gsutil -m rm -r "; print}' > /tmp/gsutil-tmp-files/remove-old-files.sh
## step 4 - I'm set the script permissions and delete old lists.
chmod 755 /tmp/gsutil-tmp-files/remove-old-files.sh
rm -rf /tmp/gsutil-tmp-files/list1.txt /tmp/gsutil-tmp-files/list2.txt
## step 5 - I run the shell script and I destroy it after it is done.
/bin/sh /tmp/gsutil-tmp-files/remove-old-files.sh
rm -rf /tmp/gsutil-tmp-files/remove-old-files.sh
There is a very simple way to do this, for example:
gsutil -m ls -l gs://bucket-name/ | grep 2017-06-23 | grep .jpg | awk '{print $3}' | gsutil -m rm -I
There isn't a simple way to do this with gsutil or object lifecycle management as of today.
That being said, would it be feasible for you to change the naming format for the objects in your bucket? That is, instead of uploading them all under "gs://mybucket/tmp/", you could append the current date to that prefix, resulting in something like "gs://mybucket/tmp/2017-12-27/". The main advantages to this would be:
Not having to do a date comparison for every object; you could run gsutil ls "gs://mybucket/tmp/" | grep "gs://[^/]\+/tmp/[0-9]\{4\}-[0-9]\{2\}-[0-9]\{2\}/$" to find those prefixes, then do date comparisons on the last portion of of those paths.
Being able to supply a smaller number of arguments on the command line (prefixes, rather than the name of each individual file) to gsutil -m rm -r, thus being less likely to pass in more arguments than your shell can handle.
I suppose I could compare the number of files in the source directory to the number of files in the target directory as cp progresses, or perhaps do it with folder size instead? I tried to find examples, but all bash progress bars seem to be written for copying single files. I want to copy a bunch of files (or a directory, if the former is not possible).
You can also use rsync instead of cp like this:
rsync -Pa source destination
Which will give you a progress bar and estimated time of completion. Very handy.
To show a progress bar while doing a recursive copy of files & folders & subfolders (including links and file attributes), you can use gcp (easily installed in Ubuntu and Debian by running "sudo apt-get install gcp"):
gcp -rf SRC DEST
Here is the typical output while copying a large folder of files:
Copying 1.33 GiB 73% |##################### | 230.19 M/s ETA: 00:00:07
Notice that it shows just one progress bar for the whole operation, whereas if you want a single progress bar per file, you can use rsync:
rsync -ah --progress SRC DEST
You may have a look at the tool vcp. Thats a simple copy tool with two progress bars: One for the current file, and one for overall.
EDIT
Here is the link to the sources: http://members.iinet.net.au/~lynx/vcp/
Manpage can be found here: http://linux.die.net/man/1/vcp
Most distributions have a package for it.
Here another solution: Use the tool bar
You could invoke it like this:
#!/bin/bash
filesize=$(du -sb ${1} | awk '{ print $1 }')
tar -cf - -C ${1} ./ | bar --size ${filesize} | tar -xf - -C ${2}
You have to go the way over tar, and it will be inaccurate on small files. Also you must take care that the target directory exists. But it is a way.
My preferred option is Advanced Copy, as it uses the original cp source files.
$ wget http://ftp.gnu.org/gnu/coreutils/coreutils-8.21.tar.xz
$ tar xvJf coreutils-8.21.tar.xz
$ cd coreutils-8.21/
$ wget --no-check-certificate wget https://raw.githubusercontent.com/jarun/advcpmv/master/advcpmv-0.8-8.32.patch
$ patch -p1 -i advcpmv-0.8-8.32.patch
$ ./configure
$ make
The new programs are now located in src/cp and src/mv. You may choose to replace your existing commands:
$ sudo cp src/cp /usr/local/bin/cp
$ sudo cp src/mv /usr/local/bin/mv
Then you can use cp as usual, or specify -g to show the progress bar:
$ cp -g src dest
A simple unix way is to go to the destination directory and do watch -n 5 du -s . Perhaps make it more pretty by showing as a bar . This can help in environments where you have just the standard unix utils and no scope of installing additional files . du-sh is the key , watch is to just do every 5 seconds.
Pros : Works on any unix system Cons : No Progress Bar
To add another option, you can use cpv. It uses pv to imitate the usage of cp.
It works like pv but you can use it to recursively copy directories
You can get it here
There's a tool pv to do this exact thing: http://www.ivarch.com/programs/pv.shtml
There's a ubuntu version in apt
How about something like
find . -type f | pv -s $(find . -type f | wc -c) | xargs -i cp {} --parents /DEST/$(dirname {})
It finds all the files in the current directory, pipes that through PV while giving PV an estimated size so the progress meter works and then piping that to a CP command with the --parents flag so the DEST path matches the SRC path.
One problem I have yet to overcome is that if you issue this command
find /home/user/test -type f | pv -s $(find . -type f | wc -c) | xargs -i cp {} --parents /www/test/$(dirname {})
the destination path becomes /www/test/home/user/test/....FILES... and I am unsure how to tell the command to get rid of the '/home/user/test' part. That why I have to run it from inside the SRC directory.
Check the source code for progress_bar in the below git repository of mine
https://github.com/Kiran-Bose/supreme
Also try custom bash script package supreme to verify how progress bar work with cp and mv comands

I'd need to see what has been changed between two directories which contain different version of a software sourcecode. While I have found a way to get a unique .diff file, how can I obtain a different file for each changed file in the two directories? I'd need this, as the "main" is about 6 MB and wanted some more handy thing.
I came around this problem too, so I ended up with some lines of a shell script. It takes three arguments: Source and destination directory (as used for diff) and a target folder (should exist) for the output.
It's a bit hacky, but maybe it would be useful for someone. So use with care, especially if your paths have special characters.
#!/bin/sh
DIFFARGS="-wb"
LANG=C
TARGET=$3
SRC=`echo $1 | sed -e 's/\//\\\\\\//g'`
DST=`echo $2 | sed -e 's/\//\\\\\\//g'`
if [ ! -d "$TARGET" ]; then
echo "'$TARGET' is not a directory." >&2
exit 1
fi
diff -rqN $DIFFARGS "$1" "$2" | sed "s/Files $SRC\/\(.*\?\) and $DST\/\(.*\?\) differ/\1/" | \
while read file
do
if [ ! -d "$TARGET/`dirname \"$file\"`" ]; then
mkdir -p "$TARGET/`dirname \"$file\"`"
fi
diff $DIFFARGS -N "$1/$file" "$2/$file" > "$TARGET"/"$file.diff"
done
if you want to compare source code it is better to commit it to a source vesioning program as "svn".
after you have done so. do a diff of your uploaded code and pipe it to file.diff
svn diff --old svn:url1 --new svn:url2 > file.diff
A bash for loop will work for you. The following will diff two directories with C source code and produce a separate diff for each file.
for FILE in $(find <FIRST_DIR> -name '*.[ch]'); do DIFF=<DIFF_DIR>/$(echo $FILE | grep -o '[-_a-zA-Z0-9.]*$').diff; diff -u $FILE <SECOND_DIR>/$FILE > $DIFF; done
Use the correct patch level for the lines starting with +++
I want to split a large text database (~10 million lines). I can use a command like
$ sed -i -e '4 s/(dB)//' -e '4 s/Best\ unit/Best_Unit/' -e '1,3 d' '/cygdrive/c/ Radio Mobile/Output/TRC_TestProcess/trc_longlands.txt'
$ split -l 1000000 /cygdrive/P/2012/Job_044_DM_Radio_Propogation/Working/FinalPropogation/TRC_Longlands/trc_longlands.txt 1
The first line is to clean the databse and the next is to split it -
but then the output files do not have the field names. How can I incorporate the field names into each dataset and pipe a list which has the original file, new file name and line numbers (from original file) in it. This is so that it can be used in the arcgis model to re-join the final simplified polygon datasets.
ALTERNATIVELY AND MORE USEFULLY -as this needs to go into a arcgis model, a python based solution is best. More details are in https://gis.stackexchange.com/questions/21420/large-point-to-polygon-by-buffer-join-buffer-dissolve-issues#comment29062_21420 and Remove specific lines from a large text file in python
SO GOING WITH A CYGWIN based Python solution as per answer by icyrock.com
we have process_text.sh

cd txt_processing
sed -i -e '4 s/(dB)//' -e '4 s/Best\ unit/Best_Unit/' -e '1,3 d' 'trc_longlands.txt'

for i in 1*; do head -n1 21aa|cat - $i > 2$i; done
for i in 21*; do echo ---- $i; cat $i; done
how can "TRC_Longlands" and the path be replaced with the input filename -in python we have %path%/%name for this.
in the last line is "do echo" necessary?
and this is called by python using
import os
os.system("process_text.bat")
where process_text.bat is basically
bash process_text.sh
I get the following error when run from dos...

why is there a "." after the directory name? how can they be given a .txt extension?
If you want to just prepend the first line of the original file to all but the first of the splits, you can do something like:
$ cat > a

Obviously, the first file will have one line less then the middle parts and the last part might be shorter, too, but if that's not a problem, this should work just fine. Of course, if your header has more lines, just change head -n1 to head -nX, X being the number of header lines.
Hope this helps.
Does anybody know if there is an rsync option, so that directories that are being traversed do not show on stdout.
I'm syncing music libraries, and the massive amount of directories make it very hard to see which file changes are actually happening.
I'v already tried -v and -i, but both also show directories.
If you're using --delete in your rsync command, the problem with calling grep -E -v '/$' is that it will omit the information lines like:
deleting folder1/
deleting folder2/
deleting folder3/folder4/
If you're making a backup and the remote folder has been completely wiped out for X reason, it will also wipe out your local folder because you don't see the deleting lines.
To omit the already existing folder but keep the deleting lines at the same time, you can use this expression :
rsync -av --delete remote_folder local_folder | grep -E '^deleting|[^/]$'
I'd be tempted to filter using by piping through grep -E -v '/$' which uses an end of line anchor to remove lines which finish with a slash (a directory).
Here's the demo terminal session where I checked it...
