I have a problem - I have files with rows of data and I need to check if the next row (of the same type) has the NEXT date in it so I need to extract a date in YYYYMMDD format from a row (easy enough) then add one day to it and compare it to the the next date I encounter on a subsequent row.
So if I have
DATE|20100530
VAL|kahskjhd

I declared a variable as int data type which was a placeholder for a resulttatus (meaning, based on the result status that variable varies from 0/1/2/3. It can contain only these four values).data type is 4 byte integer in C#. But I can declare this variable as which represents a 1 byte integer. Since that variable contains only 1 or 2 or 3 or 4, declaring the variable asis wastage of memory space.Before declaring any variable we need to just think of the memory space needed for that variable, our requirement,
View 6 Replies View Relatedin c/c++, double is usually 8 bytes. It has a 52-bit mantissa (or significand, or base), an 11-bit exponent, and a 1-bit sign. My question is: is the mantissa a 52-bit integer? Or is the decimal point just after the first bit. Meaning: if the mantissa was 1000110011100011 (in binary) would that make the value of the mantissa (assuming the exponent was 0) 1000110011100011, or 1.000110011100011? (in binary)

how to convert a dictionary data-type to a string?
actually I am trying to update some json file 's dictionary.
I need to create an out put file, last two columns as a row of data (using the first columns as heading) with the file name as first row. For an example the out put file should look like; system_name,0900_in,1000_in,1100_in,1200_in,1300_in,1400_in,0900_out,1000_out,1100_out,1200_out,1300 _out,1400_out

I need to run a script to do above conversion. Need your help.
In my system around 73gb(pc-desktop) i have,1 primary partition(windows)-25gb, 1-extended partition(remaining gb) 3 logical partitions were there in (under) extended partition in one of the logical partition is d:drive. in my hard disk d: drive is -/dev/sda5
previosly i was fat -file system , (d:drive-/dev/sda5), i remember i changed the d: drive(d:drive-/dev/sda5) file system to ext4file system ,with following command using terminal
After doing(changing the file system)this one ,i couldnt see the d:drive data
By doing that
1q) Did i reformatted the partition? i think the new filesystem(ext4) has no knowledge of the data that was on it when it had a FAT filesystem.
2q) How to do undo operation,i tried to change the filesystem type to fat/ntfs in terminal using command --sudo mkfs -t FAT /dev/sda5.
Result:its showing text message-'mkfs.FAT: No such file or directory'(not in single quote)

I have a script that checks a folder for zip files than moves them to a different folder. I want to check every 5 maybe 10 seconds and since cron is setup to run at least a 1 minute increment I'm not sure how to do that time check as probably a loop within the script. One other thing is once the time check is in the script how would a cron job be setup to run this script? Once the script is running cron doesn't need to run it again, is there a feature to check if it's running and if it's not then run it?
find /export/xxxshare -name "*.zip" -exec mv {} /export/store ;

View 5 Replies View RelatedI need a script that dose the following checks if files exists by read input from a file then compares them to the files listed in the directory if they don’t exists the script would report back which file dose not exists. I also need to format the output so that files are grouped in different groups, group A, B, and C and etc based on file name. I would like the output of that do not exists files to be sorted based on second number in the file name than group according. I understand some of the basics of bash scripting something along of the lines of a loop and if statements might do the trick. Below is what I have so far. I don’t car so much about the script reporting back the file exists I prefer to only know if the file is missing and is less than 3 days old. Problem is if a file dose not exists in the reports file the test compares against the wrong file.

I have mounted a windows share folder on /mnt. When i gave any directory within /mnt/ to stat function it fails with errorno 75. perror shows "Value too large for defined data type". Example 1 is fail but Example 2 works fine.
I have a folder which includes bunch of folders each having data files in them. [ Folder A has F1, F2 F3 ..... F1000 folders in it, and F1, F2, F3 ... each has about 10 different files named FILE 1, FILE2, FILE3 .... in them.
I am interested in File 1 of each Folder, because that contains the data I need in it. More specifically, that File1 s have a line "ANSWER=..." in them, and i need to get that value of the ANSWER from each file. So doing it by hand is so hard, so I need to write a script that will scan all folders and give me a list of values of eache ANSWERs.
I am trying to develop a method of reading files generated by other programs. I am trying to find the most versatile approach. I have been trying bash, and have been making good progress with sed, however I was wondering if there was a "standard" approach to this sort of thing. The main features I would like to implement concern reading finding strings based on various forms of context and storing them to variables and/or arrays. Here are the most general tasks:
a) Read the first word(or floating point) that comes after a given string (solved in another thread)
b) Read the nth line after a given string
c) Read all text between two given strings
d) Save the output of task a), task b) or task c) (above) into an array if the "given string(s)" is/are not unique.
e)Read text between two non-unique strings i.e. text between the nth occurrence of string1 and the mth occurrence of string2
As far as I can tell, those five scripts should be able to parse just about any text pattern. I am by no means fluent in these languages. But I could use a starting point. My main concern is speed. I intend to use these scripts in a program that reads and writes hundreds of input and output files--each with a different value of some parameter(s).
The files will most likely be no more than a few dozen lines, but I can think of some applications that could generate a few hundred lines. I have the input file generator down pretty well. Parsing the output is quite a bit trickier. And, of course, the option for parallelization will be very desirable for many practical applications.
I need to write shell script which can take number of files and count total rows from all CSVs and display total number of rows counted in all files. Is there any possibility of doing that using shell script and if yes then how.

I have very little linux experience. And need some help with a bash script. I need to a script I can set cron to run to sort files out of a holding folder into final folders. It doesn't necessarily have to be bash, but I think it would be sufficient for this. File names are formatted as such when created: Dest-Date-Time-CID-Destination# I want the files to be moved from a all in one holding folder to a folder structure like this.
.../storage/year/month/day/Destination#/VarX(type)/hour/CID/'File'
I would need an if/else if/else statement to say if Dest = A set VarX = B If for example the file name was
infinity-20100927-17:00-1112223333-4445556666.wav
I would like the above file to end up moved from
.../holding
to
.../storage/2010/09/27/4445556666/Inbound/17/1112223333/infinity-20100927-17:00-1112223333-4445556666.wav
So the script will need to make directories based on information in the file name which is delimited by single dashes. Then move files from the holding folder to the newly created "sorted" folders.
