I have this code:
Code:
original_content=${content[@]};
echo ${#content[@]} # is 23
echo ${#original_content[@]} # is 1
I'd expect original_content should be copy of content. How to copy array?
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.

[code]....
Is it possible to have an array in Bash that can hold more than one value per item?
For example I would like an array like this:
Entry 1: apple, green
Entry 2: banana, yellow
And be able to call the fruit names and their colour in a list. Something like:
for fruit in "${array[@]}"
do
echo a $fruit is $colour
done
If that is possible, is there a limit to values per item? For example some entries in an array could be:
Entry 1: apple, green, round, pips, tree
Entry 2: banana, yellow, long, skin, tree
And I would like to pick out the values such as #3 being "round" and "long".
I am using gnu bash 3.2I need to split the string into array like
a=this_is_whole_world.file # split [_.]
I need to split this on _ and . some thing like this
a[0]=this
a[1]=is
a[2]=whole
a[3]=world
a[4]=file
preferable using bash regex. if not sed is also ok.
I'm trying my hand at arrays in bash for a backup script. Now I not sure if this is the correct thing to do and just look at website and amended but does'nt work. Could someone tell me where I'm going wrong

Code:
test=(1 2 3 4 5)
for car in ${test[@]}
do
echo "Element : $car"
[code]....
if variable $car equals 1, new element is added "6" to an array. But i don't know why when i am printing all elements of this array (echo "Element : $car") this element ("6") is not mentioned, but if i make a command which check an amount of contained elements by array it will be 6 elements.
I have the following function that does not iterate through the array I want to be able to do some manipulation on each element in the array[@].it appears the below array has only one item in the array whereas i want the array to have 3 items hence the loop three times printing the message Any ideas why this is not happening ?
function foo() {
name =$1
array=( "$2" )

How could I feed this into an array, with each element containing everything between the <status> </status> tags?
I need to know how to assign a result from a select. I am clueless on the sytax. I am trying this in bash. Maybe I am not assigning the array right. It gives me the whole row in the echo instead of just field a. How do I get fieldA = a in the select. Note script was stripped for security on database info but the syntax is same.
Code:
#!/bin/sh
results="$(mysql --user ${DB_USER} -p${DB_PWD} ${DB_NAME} -Bse 'select a,b,c,d from tblMytable')"
for rows in "${results[@]}"
do
fieldA=${rows[0]};
echo ${fieldA};
done
Code:
#loop until there are no more files
while [ ${#files[@]} -gt 0 ]; do
for num in `seq 1 ${#files[@]}`; do
wurd=`tail -4 ${files[$num-1]}`
[code].....
Everything works.. but when it has to unset.. it breaks.. it doesnt give an error though.. it just jams the program.
I am trying to do this:
1. Read csv delimited file line1 and store all values in array
2. Use the values stored in the array and replace values in other text file with them
3. read line2 in the cvs file and repeat the process
4. Do above for all lines in the cvs file
for example:
file1.cvs content:
text1,text2,text3,"text 4"
a1,a2,3,"a 4"
file.txt content:
some text $array1$ some text
some text $array2$ some text
1. read line 1 - text1,text2,text3,"text 4" put each value in array X[] lines that contain spaces in cvs will have double quotes
2. read x[1] and replace value $array1$ (in file.txt) with x[1]read x[2] and replace value $array2$ (in file.txt) with x[2] and so on
Can above be accomplished in BASH and how?
This may be a basic bash array/string operation related question, but I couldn't find any direct answer. So here it goes:I have a lot of data sorted in various directories. All directories need same processing except for a special group of directories. I have a symbolic link of the script in discussion in each directory. I want the script to get the name of the current directory, check if that belongs to special group and do specific operations.So I get the name of the directory
Code:
mm=`basename `pwd``
Now the the group of directories that needs something different to be done, contains these
[code]...
I would like to read unix file permissions into a bash array for processing but tbh I have no idea how to do this. Then I will check for each individual access right l, d, x etc.
View 11 Replies View RelatedI have a command that outputs n lines of text, and I want to place each line into an array element, but I can't seem to get the syntax correct
So my command is this:
cat $configfile | sed -n '/cluster:'$clustername'/,/cluster/ p' | awk /host/
Which produces many lines depending on the value of $clustername. I'd like to get each line as elements of an array.
PI'm trying to write a script to list all open ports in the MINIUNPND chain in iptables and use the procotol, port and destination ip to open ports on another router using upnpc.Here is the output of iptables -L MINIUPNPD
Code:
>iptables -L MINIUPNPD
Chain MINIUPNPD (1 references)
target prot opt source destination
ACCEPT tcp -- anywhere 192.168.3.124 tcp dpt:19955
ACCEPT tcp -- anywhere 192.168.3.124 tcp dpt:20054
ACCEPT tcp -- anywhere 192.168.3.130 udp dpt:10654
ACCEPT tcp -- anywhere 192.168.3.121 tcp dpt:29955
code....
No matter what i do i cant seem to remove the first 4 characters from the MYPROT array to leave only the digits. Also i cant seem to read the array back???
I thought it would simply be a loop reading each line and passing the fields in variables, executing upnpc commands i need then moving to the next line of the file until it reached the EOF.
I have been trying to write a simple snip of bash shell code to import from 1 to 100 records into a Bash array.
I have a CSV file that is structured like:
record1,item1,item2,item3,item4
record2,item1,item2,item3,item4
record3,item1,item2,item3,item4
record4,item1,item2,item3,item4
And would like to get this data into corresponding arrays as such:
$record1[item1-4]
$record2[item1-4]
$record3[item1-4]
$record4[item1-4]
This _almost_ works. I just can't quite get it to honor the spaces.
Code:
#!/bin/bash
profiles=(
PROFILE_ONE
)
PROFILE_ONE=(setting1 "setting number 2")

I have an array called arrayini which stores numbers. I want to take log to the base 2 of each of the numbers in that array and put it in file called result. I've used the following code to do it.
Code:
size=${#arrayini[@]}
for ((i=0;i<size;i++))
do
echo "scale = 12; l(${arrayini[$i]})/l(2)" | bc -l
done >result
It works fine but its taking pretty long to calculate since I've got about 230,000 items in the array. So I decided to store the result into an array hoping that it'd be faster. I tried the following code. arrayresult is where I try and store the result. The code doesn't work because of the second last line.
Code:
unset arrayresult
size=${#arrayini[@]}
for ((i=0;i<size;i++))
do
arrayresult[$i]="scale = 12; l(${arrayini[$i]})/l(2)" | bc -l
done >FILE2
There is a syntax error clearly.
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 have one questions :"bash copy filename destin_dir"1- i need a bash script to copy file from one directory to another , and if the destination directory have the same file name, add '_1' to the file name ..and if there is a file with 'filename_1' , add '_2' to the file name and become 'filename_2' and so on

View 16 Replies View RelatedI need a script to copy music from a network drive to my local disk. I require the script to auto mount the remote server, then to create the directory path to the mp3's I have a list of all teh songs in the following format, note some have spaces.
\7800SPARE4UsersPublicMusicSample MusicKalimba.mp3 \7800SPARE4UsersPublicMusicSample MusicMaid with the Flaxen Hair.mp \7800SPARE5UsersPublicMusicSample Song Sleep Away.mp3
I can use the following to mount the directory:
mount -t cifs //7800SPARE4/Users /dest-o username=user,password=pass
I'm thinking the best way would be to get the share name 7800SPARE and the grep for all these in the list, then mount it and do a while read LINE However I would need to creat the folders, I am unsure on how to do this. I think I would need to sed the backslashes to forward ones and then use rsync? Then unmount and move on to the next ones, if I can't mount the share It would be nice to log it and skip it.

How to convert this to a char array?
I'm writing a PHP program. I've encountered a problem; in the following code I try to pass $_POST['delete'] which is an array as the value of a hidden input to some form, but it doesn't do so.there's something wrong with converting PHP array into HTML array. I'm sure that $_POST['delete'] is not null and is a real array.
echo '<input type="hidden" name="delete[]" value="'.$_POST['delete'].'" />';
