Oct 2, 2010the project I'm working on requires parsing a text file with fields separated by the | char and using perl to insert/update a mysql database. Some of the fields are simple numeric and others are text fields. In some of the text fields I run into a problem creating a proper insert statement for the perl api to mysql if I don't escape the single quote (') char with a backslash (). I can take each text file and do a manual subsitutiton, but I would prefer to use the script that prepares the text file to do it for me. I've tried sed (ex: sed s/'/\'/g ) and it runs cleanly, but does nothing to accomplish my goal. I suppose I could write a function to read the file character by character and write it out that way, but it seems a waste.

Apr 1, 2009I am trying to copy a large number of files from a Linux server to a Windows file share.

So now I'm trying to come up with a way to change the file and folder names on the fly to replace the colons with a dash "-" or space " ".

I've found that making a for loop does not work with files that contain a space in the name. Something to due with a bug that they call a "feature" that stops the first variable at the first whitespace.
Using a "while" loop is not exactly what i require either seeing as I want to be able to view each image in the directory on screen and tag it accordingly, before it jumps off to the next image, and I'm not sure how to add a pause to a while loop.
How do I make a Bash script and loop Variables handle files like "files that contain spaces.jpg"

View 4 Replies View RelatedProgramming :: Bash File Names Different Than Openbox Trash
Feb 14, 2011Im writing my first bash script. Its function is to move files to the trash can and write a log file in the same format that the system does to allow for file restoration. The problem is that in bash, everything works fine, but in the OpenBox window session, the files are named after the source directory, not the original name. Heres the script:
Code:
#!/bin/bash
# trash - Script to move file or folder to the trash can and create a log file
##### Functions #####
err_output () # Writes error message {
echo "$0: cannot stat `$1': No such file or directory"
echo "USAGE: $0 SOURCE DEST"
exit 1 } >&2
write_log_numbered ()
# Writes log entry for numbered files {
echo "[Trash Info]" > $HOME/.local/share/Trash/info/${FILE}.$max.trashinfo
echo "Path="$PWD >> $HOME/.local/share/Trash/info/${FILE}.$max.trashinfo
echo "DeletionDate="`date "+%Y-%m-%dT%H:%M:%S"` >> $HOME/.local/share/Trash/info/${FILE}.$max.trashinfo
}
write_log_unique () # Writes log entry for unique files {
echo "[Trash Info]" > $HOME/.local/share/Trash/info/${FILE}.trashinfo
echo "Path="$PWD >> $HOME/.local/share/Trash/info/${FILE}.trashinfo
echo "DeletionDate="`date "+%Y-%m-%dT%H:%M:%S"` >> $HOME/.local/share/Trash/info/${FILE}.trashinfo
} make_paths () # Makes necessary folders {
mkdir -p ~/.local/share/Trash
mkdir -p ~/.local/share/Trash/files
mkdir -p ~/.local/share/Trash/info
}
##### Main #####
make_paths
SOURCE="$1"
DEST=$(dirname ~/.local/share/Trash/files/filename)
[ -e "$SOURCE" ] || err_output "$SOURCE"
[ -d "$DEST" ] || err_output "$DEST"
FILE="$(basename "$SOURCE")"
if [ -e "${DEST}/${FILE}" ]; then
max=0 DIR="$(pwd)" cd "$DEST"
shopt -s nullglob for backup in "${FILE}."; do
nr=${backup#${FILE}.}
if [[ "$nr" =~ ^[0-9]+$ ]]; then
if (( nr>max )); then
max="$nr" fi
fi
done
cd "$DIR"
max=$(( max + 1 ))
write_log_numbered
mv -- "$SOURCE" "${DEST}/${FILE}.$max"
else
write_log_unique
mv -- "$SOURCE" "$DEST/${FILE}"
fi
So I run the script with the test file "Junk". In bash, it moves over and its named correctly.
Code:
~/.local/share/Trash/files$ ls
file file.1 Files Files.1 Junk
The log file is also named correctly
Code:
~/.local/share/Trash/info$ ls
file.1.trashinfo Files.1.trashinfo Files.trashinfo file.trashinfo Junk.trashinfo
But, when I go to view the trash can in the file manager in Openbox, the file is called "Testing" which is the name of the source directory. However, if I go to the trashcan via its full path (going to .local/, then share/) all the files are named correctly. Whats going on here? Is there some way to get the trash can to read the correct file name?
Programming :: Using Key To Match Against Source.txt File To Add Xml Tags To Names In Perl
Jun 21, 2010Using a list of names (over 4000 of them) painstakingly gleaned from the source file years ago for a database file, I want to match the names against the source file so that they can be updated with the tags <forename></forename> in the original source file.
I placed the list of names in @forenames (only posted a few of them here).
Perl script is:
I am able to get the name bracketed by the tags to appear on the console screen but don't know how to apply the output to the source file. Perhaps I need to do a match on the words then some kind of edit to surround the matching words with the xml tags? I'm a rank novice doing this as a labour of love for a friend.

View 2 Replies View RelatedGeneral :: Dual Domain Names On A Single Network?
Aug 10, 2010Here is my scenario and what I want to try and achieve.
I have:
Quote:
Server A = 192.168.1.5 (serverA.home.com)
Server B = 192.168.1.6 (serverB.home.com)
Currently I have serverA.home.com domain name set up using a free dns service online. When I am anywhere in the world I just type the domain name it hits my static ISP IP via the free dns servers online, hits my home router, gets port forwarded to 192.168.1.5 Server A and I am up and running.
Now...
I have bought a second domain for serverB and want it set up like serverA but I am totally baffled on how I can resolve 2 domain names on a single network? I need (somehow) to try and tell the dns servers that when I enter in serverB.home.com it will hit my static ISP IP as above and then hit my home router but then get directed/split to Server B and not to Server A.
Basically all I want to do is name the machines and get traffic resolved to them.

Nov 13, 2010I have a huge binary log file. There are lets say 4 id's that I want to find in a log file. I know that those 4 id's will be present in the log file and I also know in what order they will be present. I want to find 1st id from the log then 2nd id and then third id and so on..
Simple/inefficient solution is: Loop through the id's and then grep in the log file. Problem with this solution is for each id grep will search from the beginning of the file.
Better/efficient solution would be: Sine I know the order in which id's will be present in the log file. Loop through id's, grep 1st id and then move on to grep 2nd id and so on...this way I can grep all id's in one pass. Is this solution possible ?
I have 500000 + values to find in log files and I have to find efficient solution for it.

Add to this, my file will grow as new entries are added (always appended to the end) but new entries will have the same formatting.
