What is the difference between single and slash here and in general?
How to copy if we have a unique directory somewhere? Is some of above ways more prefered or... better solutions exists???

use code tags, please!
I guess, its usually ignored by the bash. Its there, where I too have observed similarly, specially while specifying paths (in Linux commands) when mis-typed to put multiple / (i.e. // or even /// )
My feeling has been that bash parses them to make only one '/' in the command parameters. There is no difference otherwise. It's just a feature in bash not available in other older shells like sh, where, I hope, you'd get an error for such mis-types.

Hi ..
I am trying to create one function.
It will have two arguments.
Argument1: a,b,d,f,g

Can anyone help with this one? (4 Replies)
In the awk I am trying to subtract the difference $3-$2 of each matching $4 before the first _ (underscore) and print that value in $13.
I think the awk will do that, but added comments. What I am not sure off is how to add a line or lines that will add sum each matching $13 value and put it in... (2 Replies)

PARALLEL-SCP(1)PARALLEL-SCP(1)NAME
parallel-scp - parallel versions of scp
SYNOPSIS
parallel-scp [OPTIONS] -h hosts.txt local remote
DESCRIPTION
pssh provides a number of commands for executing against a group of computers, using SSH. It's most useful for operating on clusters of
homogenously-configured hosts.
parallel-scp copy files in parallel to a set of machines.
OPTIONS -r --recursive
recusively copy directories (OPTIONAL)
-h --hosts
hosts file (each line "host[:port] [user]")
-l --user
username (OPTIONAL)
-p --par
max number of parallel threads (OPTIONAL)
-o --outdir
output directory for stdout files (OPTIONAL)
-e --errdir
output directory for stderr files (OPTIONAL)
-t --timeout
timeout (secs) (-1 = no timeout) per host (OPTIONAL)
-O --options
SSH options (OPTIONAL)
-v --verbose
turn on warning and diagnostic messages (OPTIONAL)
EXAMPLE
The following example runs hostname on three machines (IPs or hostnames) specified in the file ips.txt using login irb2 and saves the
output in /tmp/foo.
# parallel-scp -h ips.txt -l irb2 /etc/hosts /tmp/hosts
Success on 128.112.152.122:22
Success on 18.31.0.190:22
Success on 128.232.103.201:22
ENVIRONMENT
All four programs take similar sets of options. All of these options can be set using the following environment variables:
o PSSH_HOSTS
o PSSH_USER
o PSSH_PAR
o PSSH_OUTDIR
o PSSH_VERBOSE
o PSSH_OPTIONS
