I have only been working with Linux for a few years now so bear with my noob question. I was wondering if there is a way to tail the most recent file that has a file name like 'scrubsncoa%'. There will be at least 2 files in the directory that start with 'scrubsncoa' and a few other different... (2 Replies)
Hey all.. This should be simple but stoopid here can't get head around it! I have many directories, say 100 each with many files inside. I need a script to traverse through the dirs, find most recent file in each dir and add it to a tar file.
I can find the files with something like

I want to find the most recent file containing ' NORESETLOGS"
I'm already here but, how to sort this now in a correct way ?
By the way, my version of find does not know about 'fprint'
find . -type f -exec grep -i " NORESETLOGS" {} \; -exec ls -l {} \; | grep -vi " RESETLOGS" (5 Replies)
How do you get your recent vi command history to show up? I keep randomly getting like my previous 5 commands and can't figure out how I'm doing it. I think it has something to do with the shift key and another button. (6 Replies)
Hi guys,
Under my root directory there are many sub-directories which contains log file for every day of running.
How can I find , in one command only, the recent log file in each sub-directory?
For example, If I run the following:
find . -name "exp_prod_*_*_yes_*_.log" -exec ls -ltr {} \;... (12 Replies)
Hello Experts...
dir of FTP will list all the files in the directory. Is there any command or option of dir that will give me the most recent file only?
Since I couldn't find any such thing, I thought of creating a log file (of FTP results) and work on this log file to determine the most recent... (2 Replies)
Very new to shell scripting. Not sure if my title is correct but I will try and explain.
Directory has 100+ files with this format, " ABCD_ABC_Abc_AB0126.abc ". When a new file gets created, the 16-19 characters in the file name gets incremented by 1. Ex...todays most recent file is... (14 Replies)
Hi,
I need to find the most recent files by their name from an X repertoire.
The problem is that the name of the files is of type:
POWERL10_20151203000.xml
POWERL10_20151203001.xml
POWERL10_20151202000.xml

shell-quote
SHELL-QUOTE(1p) User Contributed Perl Documentation SHELL-QUOTE(1p)NAME
shell-quote - quote arguments for safe use, unmodified in a shell command
SYNOPSIS
shell-quote [switch]... arg...
DESCRIPTION
shell-quote lets you pass arbitrary strings through the shell so that they won't be changed by the shell. This lets you process commands
or files with embedded white space or shell globbing characters safely. Here are a few examples.
EXAMPLES
ssh preserving args
When running a remote command with ssh, ssh doesn't preserve the separate arguments it receives. It just joins them with spaces and
passes them to "$SHELL -c". This doesn't work as intended:
ssh host touch 'hi there' # fails
It creates 2 files, hi and there. Instead, do this:
cmd=`shell-quote touch 'hi there'`
ssh host "$cmd"
This gives you just 1 file, hi there.
process find output
It's not ordinarily possible to process an arbitrary list of files output by find with a shell script. Anything you put in $IFS to
split up the output could legitimately be in a file's name. Here's how you can do it using shell-quote:
eval set -- `find -type f -print0 | xargs -0 shell-quote --`
debug shell scripts
shell-quote is better than echo for debugging shell scripts.
debug() {
[ -z "$debug" ] || shell-quote "debug:" "$@"
}
With echo you can't tell the difference between "debug 'foo bar'" and "debug foo bar", but with shell-quote you can.
save a command for later
shell-quote can be used to build up a shell command to run later. Say you want the user to be able to give you switches for a command
you're going to run. If you don't want the switches to be re-evaluated by the shell (which is usually a good idea, else there are
things the user can't pass through), you can do something like this:
user_switches=
while [ $# != 0 ]
do
case x$1 in
x--pass-through)
[ $# -gt 1 ] || die "need an argument for $1"
user_switches="$user_switches "`shell-quote -- "$2"`
shift;;
# process other switches
esac
shift
done
# later
eval "shell-quote some-command $user_switches my args"
OPTIONS --debug
Turn debugging on.
--help
Show the usage message and die.
--version
Show the version number and exit.
