Hello
when I try to run rm on multiple files I have problem to delete files with space.
I have this command :
find . -name "*.cmd" | xargs \rm -f
it doing the work fine but when it comes across files with spaces like : "my foo file.cmd"
it refuse to delete it
why? (1 Reply)
Question for anyone that might be able to help:
My objective is to eheck if a file (a source file) exists in a directory. If it does then, I'd like to call an application (Informatica ETL file...not necessary to know) to run a program which extracts data and loads it into multiple targets.

Hi,
I want to run a Perl script on multiple files, with same name ("Data.txt") but in different directories (eg : 2010_06_09_A/Data.txt, 2010_06_09_B/Data.txt).
I know how to run this perl script on files in the same directory like:
for $i in *.txt
do
perl myscript.pl $i > $i.new... (8 Replies)
Hi
I have 1000 files labelled data1.txt through data1000.txt. I want to write a script that prints out the number of lines in each txt file and outputs it in the following format:
Column 1: number of data file (1 through 1000)
Column 2: number of lines in the text file
Thanks! (2 Replies)
Hi everyone,
I'm new to the forums, as you can probably tell... I'm also pretty new to scripting and writing any type of code.
I needed to know exactly how I can grep for multiple strings, in files located in one directory, but I need each string to output to a separate file.
So I'd... (19 Replies)

How can I run the following command on multiple files and print out the corresponding multiple files.
perl script.pl genome.gff 1.txt > 1.gff
However, there are multiples files of 1.txt, from 1----100.txt
Thank you so much.

I have a script that I need to run on one file at a time. Unfortunately using for i in F* or cat F* is not possible. When I run the script using that, it jumbles the files and they are out of order. Here is the script:
gawk '{count++; keyword = $1}
END {
for (k in count)
{if (count == 2)... (18 Replies)

tabix
tabix(1) Bioinformatics tools tabix(1)NAME
bgzip - Block compression/decompression utility
tabix - Generic indexer for TAB-delimited genome position files
SYNOPSIS
bgzip [-cdhB] [-b virtualOffset] [-s size] [file]
tabix [-0lf] [-p gff|bed|sam|vcf] [-s seqCol] [-b begCol] [-e endCol] [-S lineSkip] [-c metaChar] in.tab.bgz [region1 [region2 [...]]]
DESCRIPTION
Tabix indexes a TAB-delimited genome position file in.tab.bgz and creates an index file in.tab.bgz.tbi when region is absent from the com-
mand-line. The input data file must be position sorted and compressed by bgzip which has a gzip(1) like interface. After indexing, tabix is
able to quickly retrieve data lines overlapping regions specified in the format "chr:beginPos-endPos". Fast data retrieval also works over
network if URI is given as a file name and in this case the index file will be downloaded if it is not present locally.
OPTIONS OF TABIX -p STR Input format for indexing. Valid values are: gff, bed, sam, vcf and psltab. This option should not be applied together with any
of -s, -b, -e, -c and -0; it is not used for data retrieval because this setting is stored in the index file. [gff]
-s INT Column of sequence name. Option -s, -b, -e, -S, -c and -0 are all stored in the index file and thus not used in data retrieval.
[1]
-b INT Column of start chromosomal position. [4]
-e INT Column of end chromosomal position. The end column can be the same as the start column. [5]
-S INT Skip first INT lines in the data file. [0]
-c CHAR Skip lines started with character CHAR. [#]
-0 Specify that the position in the data file is 0-based (e.g. UCSC files) rather than 1-based.
-h Print the header/meta lines.
-B The second argument is a BED file. When this option is in use, the input file may not be sorted or indexed. The entire input will
be read sequentially. Nonetheless, with this option, the format of the input must be specificed correctly on the command line.
-f Force to overwrite the index file if it is present.
-l List the sequence names stored in the index file.
EXAMPLE
(grep ^"#" in.gff; grep -v ^"#" in.gff | sort -k1,1 -k4,4n) | bgzip > sorted.gff.gz;
tabix -p gff sorted.gff.gz;
tabix sorted.gff.gz chr1:10,000,000-20,000,000;
NOTES
It is straightforward to achieve overlap queries using the standard B-tree index (with or without binning) implemented in all SQL data-
bases, or the R-tree index in PostgreSQL and Oracle. But there are still many reasons to use tabix. Firstly, tabix directly works with a
lot of widely used TAB-delimited formats such as GFF/GTF and BED. We do not need to design database schema or specialized binary formats.
Data do not need to be duplicated in different formats, either. Secondly, tabix works on compressed data files while most SQL databases do
not. The GenCode annotation GTF can be compressed down to 4%. Thirdly, tabix is fast. The same indexing algorithm is known to work effi-
ciently for an alignment with a few billion short reads. SQL databases probably cannot easily handle data at this scale. Last but not the
least, tabix supports remote data retrieval. One can put the data file and the index at an FTP or HTTP server, and other users or even web
services will be able to get a slice without downloading the entire file.
