...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 am trying a search for a pattern in the file. I can have any character in the pattern. I am pretty sure I will have $, ", ', ^, ` etc., The Problem I am facing is if I use "" (double quotes) to enclose the pattern, it gives special meaning to $, ^ and " within the string. I have no control over the pattern input. I am getting it from some other file. On the other hand, If I use '' (single quotes) to enclose the pattern, it gives special meaning to the ' (apostrophe) within the string and terminates the pattern prematurely. How do I disable the special meaning these characters have? For example, in perl, I could enclose the pattern within Q and E. Is there an equivalent in grep pattern expression? I could find one in the man page of grep. Is there a solution to this problem?

View 14 Replies View RelatedI'm trying to search for several strings, which I have in a .txt file line by line, on another file.
So the idea is, take input.txt and search for each line in that file in another file, let's call it rules.txt.
So far, I've been able to do this, to search for individual strings:
Code: Select allimport re
shakes = open("output.csv", "r")
for line in shakes:
if re.match("STRING", line):
print line,
How can I change this to input the strings to be searched from another file?
So far I haven't been able to.

I am looking for an easy way to convert any given maze.txt of any size to a internal array of strings(dynamically allocated). Important is that dimensions of the maze (row, col) shouldn't be written by the user instead they have to be somehow read from the file. This is not my homework assignment! It is a small part of a project that i never dealt with. I never read files to C string.... I made it for specific maze dimensions, but want it to work with any given .txt file.
View 9 Replies View RelatedI'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 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.

(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:
Quote:
#/bin/bash
RED=$(tput setaf 1)
BLK=$(tput setaf 0)
[code]....
*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.
i have an array var=(node1,node2,node3,node4) and i want to shuffle the array elements randomly every time when unix script will run like that.....
first time when script run order will be shuffle randomly
node3,node1,node4,node2
second time when script run order will be shuffle randomly like
node1,node4,node2,node3
third time when script will run again order will be shuffle randomly like
node2,node1,node3,node4

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 $colour
done
If that is possible, is there a limit to values per item? For example some entries in an array could be:
Entry 1: apple, green, round, pips, tree
Entry 2: banana, yellow, long, skin, tree
And I would like to pick out the values such as #3 being "round" and "long".
I have this code:
Code:
original_content=${content[@]};
echo ${#content[@]} # is 23

I am using gnu bash 3.2I need to split the string into array like

I need to split this on _ and . some thing like this
a[0]=this

a[2]=whole
a[3]=world
a[4]=file
preferable using bash regex. if not sed is also ok.

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 ?

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.

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

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]
