Your shell - which you failed to mention, BTW - should provide the -x (xtrace) option to print to stderr the commands / lines it is about to execute.
One option to accelerate the script would be to optimise the order in which the files are accessed / evaluated, and to drop the for loops. On top, there's no need to read the files' file again and again, if the files don't change with the respective servers. Read once and build the scp into a variable.Try something along
Code:
readarray FNARR < filesfile
while read SVNM
do CHKDIR/MKDIR serverdir
scp -options $SVNM/${FNARR[@]} serverdir
done < serverfile
copying all target files from a single server in one go... This is an untested frame / pseudo code proposal, so YMMV.
Hello all,
This beats me. I have a script that executes some commands and redirects their output to some text files that I will parse. The commands are along the lines of:
dsmadmc -id=admin -pa=admin -outfile=/home/tools/qlog.txt q log f=d
If I just run the script it works. If I execute... (2 Replies)

One of our servers runs Solaris 8 and does not have "ls -lh" as a valid command. I wrote the following script to make the ls output easier to read and emulate "ls -lh" functionality. The script works, but it is slow when executed on a directory that contains a large number of files. Can anyone make... (10 Replies)
Hello,
So my knowledge of bash scripting is not that great and I have been trying to solve this problem on my own for awhile to no avail.

Hi all,
In bash scripting, I use to read files:
cat $file | while read line; do

doneHowever, it's a very slow way to read file line by line.
E.g. In a file that has 3 columns, and less than 400 rows, like this:
I run next script:

rbash
RBASH(1) General Commands Manual RBASH(1)NAME
rbash - restricted bash, see bash(1)RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is
used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow-
ing are disallowed or not performed:
o changing directories with cd
o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV
o specifying command names containing /
o specifying a filename containing a / as an argument to the . builtin command
o specifying a filename containing a slash as an argument to the -p option to the hash builtin command
o importing function definitions from the shell environment at startup
o parsing the value of SHELLOPTS from the shell environment at startup
o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators
o using the exec builtin command to replace the shell with another command
o adding or deleting builtin commands with the -f and -d options to the enable builtin command
o using the enable builtin command to enable disabled shell builtins
o specifying the -p option to the command builtin command
o turning off restricted mode with set +r or set +o restricted.
These restrictions are enforced after any startup files are read.
When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script.
