General :: Bash Shell Scripting Request?

Feb 27, 2011

I am working on a simple script that should take two command line arguments, a [number] and a [name]. The first thing the script should do is check to make sure that no more and no less than two command line arguments have been entered when calling the script - an error message should be delivered if the condition is not true.

If two args have been entered, then the message 'processing "scriptname"' should appear, where scriptname is the name of the script being called. The script should then write to the screen "Hi [name]!", and should write this phrase [number] of times. For example, the command $ myscript 2 joe would produce the output: I have read the manual many times looking for examples, and I am very close by virtue of my own efforts. Further, I have searched these forums and others for good examples, which have also gotten me very close. Still my script is not completing the objective, and I am wondering if someone could point me in the right direction. Script:

I tried ch[$1]++, ch[$1]+1, ch[$1++], ch[$1]+=1, ch[$1]=ch[$1]+1 none of these seem to work.
# while loop reading from read.txt for check list 1 - 15
for i in `seq 15`

General :: Shell Scripting: Getting Multiple Input Files For An Application?

Sep 21, 2010

I am running an application called QuantiSNP [URL]. The binary file is "quantisnp2", called upon in the "run_quantisnp2.sh" supplied by the authors. I am only able to run the application for single file processing (e.g. 1 input file for 1 sample; I can't run the batch file processing because I don't have the necessary BeadStudio report files, which has different formatting for the input files).

The difficulty is that I have 300 samples (300 unique sample IDs) and 3 input files for each sample for a total of 900 runs of this application. I am wondering how would I be able to automate this process as a shell script instead of basically manually changing the sample ID and respective input files every time a run completes? I bolded the single file processing shell script command line options below that need to be changed for each sample/input single file processing run. The command line option "--sampleid" is for the name given to the processed output files corresponding to the sample of interest and there are 3 input files for each sample.

/home2/jason/QuantiSNP/quantisnp/linux64/run_quantisnp2.sh /home2/jason/QuantiSNP/MCR/v79/ --config /home2/jason/QuantiSNP/quantisnp/config/params.dat --levels /home2/jason/QuantiSNP/quantisnp/config/levels-affy.dat --outdir /home2/jason/QuantiSNP/quantisnp_out/ --sampleid sample1 --gender female --input-files /home2/jason/files/sample1_input.txt

Note that each sample has 3 input files, for a total of 3 runs of "quantisnp2" for each sample. e.g.

SAMPLEID INFILE
sample1 /home2/jason/files/sample1_input.txt
sample1 /home2/jason/files/sample1_input2.txt
sample1 /home2/jason/files/sample1_input3.txt

[code]....

General :: Bash Scripting - Removing Strings From MP3 Filenames

Oct 5, 2010

I've been surfing and searching the net quit a while now to make my own script, but I haven't been really successful ever since I want to make a script which can remove strings from my mp3 collection (file names).

For example:
Code:
101-bob_sinclar_feat_sean_paul-tik_tok_(radio_edit).mp3 --> bob_sinclar_feat_sean_paul-tik_tok_(radio_edit).mp3
10-Young Jeezy-Lose My Mind (78 Bpm) (Repack).mp3 --> young_jeezy-lose_my_mind.mp3

Now the problem is how can I remove the strings like:
101 & 10 (dynamic)
(%%% Bpm) (dynamic)
(Repack) (static)
