I have a question regarding unix loops. I want to run 100 commands using file1.txt-file100.txt in parallel. I use the code below and it works well. But now I want to run first 20 commands first using file1.txt-file20.txt in parallel, then when they are completed, run the next 20 commands in parallel, then the next 20 commands ... and so on. But I don't know how to modify the code to do that. Does anyone know how to write the code? Thank you for your time and help in advance.
Code:
for snplist in $(seq 1 100); do plink --bfile mydata --extract file${snplist}.txt --make-bed --out file${snplist}& done
thanks,
Lin

Hi, I am writing a bash shell script. I will have a section of code devoted to a for loop:
for FILE in *.hdf *.L2; do
echo hello world
done
The complication is that sometimes there will not be any files with a ".hdf" extension, or sometimes there won't be any with a ".L2" extension. Since... (4 Replies)
Hi all
Sorry for the basic question, but i am writing a shell script to get around a slightly flaky binary that ships with one of our servers. This particular utility randomly generates the correct information and could work first time or may work on the 12th or 100th attempt etc !.... (4 Replies)

pts_source
PTS_SOURCE(1) AFS Command Reference PTS_SOURCE(1)NAME
pts_source - Read pts commands from a file
SYNOPSIS
pts source [-file] <file name> [-cell] <cell name>
[-noauth] [-localauth] [-force]
pts so [-f] <file name> [-c] <cell name>
[-n] [-l] [-f]
DESCRIPTION
The pts source runs commands from a file as if they were typed in pts interactive mode. The command can be run from the command line or
interactively.
CAUTIONS
Prior to OpenAFS 1.4.5 and OpenAFS 1.5.23, the pts source command was only available on Unix or Linux and when OpenAFS was compiled with
the supergroups option (disabled by default). As of OpenAFS 1.4.5 and 1.5.23, it is always available.
OPTIONS
pts source takes the following options:
-cell <cell name>
Names the cell in which to run the command. For more details, see pts(1).
-force
Enables the command to continue executing as far as possible when errors or other problems occur, rather than halting execution at the
first error.
-help
Prints the online help for this command. All other valid options are ignored.
-localauth
Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile file. Do not combine this flag with the -cell or
-noauth options. For more details, see pts(1).
-noauth
Assigns the unprivileged identity anonymous to the issuer. For more details, see pts(1).
OUTPUT
This command shows the output of each command in the file as if it were run normally.
EXAMPLES
Here is an example of using pts source in a pts interactive session:
% echo examine admin > /tmp/commands.txt
% pts interactive
pts> source /tmp/commands.txt
Name: admin, id: 1, owner: system:administrators, creator: anonymous,
membership: 2, flags: S----, group quota: 20.
pts> quit
