I'm writing a script to find the oldest file in a directory. I know this can be done by using ls -rt | tail -1 but these are rather large directories and that can be somewhat slow since the script will be running constantly.
Are there any other ways to do this that would be faster? I looked to... (2 Replies)
Hi all,
I need your assistance in removing the oldest file in a directory.
I posted the same thread 3 days back and I got the following answer
ls -1 -t | tail -1 | xargs rm
which is not covering the case when there are directories older than the oldest file.
So, could you please... (2 Replies)
Hi all,
I am a newbie to scripting and I need your help regarding finding the oldest file in a particular directory. My intention is to remove that oldest file.
Are there any options available with the "find" command to do this..
Thanks in advance for your help

I have the following script and would like to know how to set the variable correctly.
FTP downloads the .rpm to the current directory, so the RPM command needs to know the directory it is in.
I could use ./test-application-1.0.i386.rpm to execute the command, but is there a way to set the... (6 Replies)
I am trying to determine the oldest and most recent files in a huge directory. I am using an ls -tr statement outside my find statement. The directory is too big and I am getting an "arg list too long" error. Is there something I can put in my find statement that doesn't create a list to... (2 Replies)
Hey! I have found similar posts both here and on other sites regarding this, but I cannot seem to get my script to work. I want to delete the oldest file in a test directory if there are more than two files. My script is currently:
#!/bin/bash
MEPATH=/usr/local/bin/test

The `bash` below uses the oldest folder in the specified directory and logs it. The goes though an analysis process and creates a log. My problem is that if there are 3 folders in the directory folder1,folder2,folder3, the bash is using folder2 for the analysis eventhough folder1 is the oldest... (0 Replies)
In the bash below the oldest folder in a directory is selected. If there are 3folders in the directory /home/cmccabe/Desktop/NGS/test and nothing is done to them (ie. no files deleted, renamed) then the bash correctly identifies f1 as the oldest. However, if something is done to the folder then... (4 Replies)

script
SCRIPT(1) BSD General Commands Manual SCRIPT(1)NAME
script -- make typescript of terminal session
SYNOPSIS
script [-adfpqr] [-c command] [file]
DESCRIPTION
script makes a typescript of everything printed on your terminal. It is useful for students who need a hardcopy record of an interactive
session as proof of an assignment, as the typescript file can be printed out later with lpr(1).
If the argument file is given, script saves all dialogue in file. If no file name is given, the typescript is saved in the file typescript.
Option:
-a Append the output to file or typescript, retaining the prior contents.
-c command
Run the named command instead of the shell. Useful for capturing the output of a program that behaves differently when associated
with a tty.
-d When playing back a session with the -p flag, don't sleep between records when playing back a timestamped session.
-f Flush output after each write. This is useful for watching the script output in real time.
-p Play back a session recorded with the -r flag in real time.
-q Be quiet, and don't output started and ended lines.
-r Record a session with input, output, and timestamping.
The script ends when the forked shell exits (a control-D to exit the Bourne shell (sh(1)), and exit, logout or control-d (if ignoreeof is not
set) for the C-shell, csh(1)).
Certain interactive commands, such as vi(1), create garbage in the typescript file. script works best with commands that do not manipulate
the screen, the results are meant to emulate a hardcopy terminal.
ENVIRONMENT
The following environment variable is used by script:
SHELL If the variable SHELL exists, the shell forked by script will be that shell. If SHELL is not set, the Bourne shell is assumed. (Most
shells set this variable automatically).
SEE ALSO csh(1) (for the history mechanism).
HISTORY
The script command appeared in 3.0BSD.
BUGS
script places everything in the log file, including linefeeds and backspaces. This is not what the naive user expects.
