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)
I am using a bash script to perform some automated maintenance on files in a directory. When I run the script using $sh -x script.sh <directory> the script works fine. It sets the variable to the oldest file, and continues on. However when I run the script like this $./script.sh <directory>, it... (5 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 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)

GIT-CLEAN(1) Git Manual GIT-CLEAN(1)NAME
git-clean - Remove untracked files from the working tree
SYNOPSIS
git clean [-d] [-f] [-i] [-n] [-q] [-e <pattern>] [-x | -X] [--] <path>...
DESCRIPTION
Cleans the working tree by recursively removing files that are not under version control, starting from the current directory.
Normally, only files unknown to Git are removed, but if the -x option is specified, ignored files are also removed. This can, for example,
be useful to remove all build products.
If any optional <path>... arguments are given, only those paths are affected.
OPTIONS-d
Remove untracked directories in addition to untracked files. If an untracked directory is managed by a different Git repository, it is
not removed by default. Use -f option twice if you really want to remove such a directory.
-f, --force
If the Git configuration variable clean.requireForce is not set to false, git clean will refuse to delete files or directories unless
given -f, -n or -i. Git will refuse to delete directories with .git sub directory or file unless a second -f is given.
-i, --interactive
Show what would be done and clean files interactively. See "Interactive mode" for details.
-n, --dry-run
Don't actually remove anything, just show what would be done.
-q, --quiet
Be quiet, only report errors, but not the files that are successfully removed.
-e <pattern>, --exclude=<pattern>
In addition to those found in .gitignore (per directory) and $GIT_DIR/info/exclude, also consider these patterns to be in the set of
the ignore rules in effect.
-x
Don't use the standard ignore rules read from .gitignore (per directory) and $GIT_DIR/info/exclude, but do still use the ignore rules
given with -e options. This allows removing all untracked files, including build products. This can be used (possibly in conjunction
with git reset) to create a pristine working directory to test a clean build.
-X
Remove only files ignored by Git. This may be useful to rebuild everything from scratch, but keep manually created files.
INTERACTIVE MODE
When the command enters the interactive mode, it shows the files and directories to be cleaned, and goes into its interactive command loop.
The command loop shows the list of subcommands available, and gives a prompt "What now> ". In general, when the prompt ends with a single
>, you can pick only one of the choices given and type return, like this:
*** Commands ***
1: clean 2: filter by pattern 3: select by numbers
4: ask each 5: quit 6: help
What now> 1
You also could say c or clean above as long as the choice is unique.
The main command loop has 6 subcommands.
clean
Start cleaning files and directories, and then quit.
filter by pattern
This shows the files and directories to be deleted and issues an "Input ignore patterns>>" prompt. You can input space-separated
patterns to exclude files and directories from deletion. E.g. "*.c *.h" will excludes files end with ".c" and ".h" from deletion. When
you are satisfied with the filtered result, press ENTER (empty) back to the main menu.
select by numbers
This shows the files and directories to be deleted and issues an "Select items to delete>>" prompt. When the prompt ends with double >>
like this, you can make more than one selection, concatenated with whitespace or comma. Also you can say ranges. E.g. "2-5 7,9" to
choose 2,3,4,5,7,9 from the list. If the second number in a range is omitted, all remaining items are selected. E.g. "7-" to choose
7,8,9 from the list. You can say * to choose everything. Also when you are satisfied with the filtered result, press ENTER (empty) back
to the main menu.
ask each
This will start to clean, and you must confirm one by one in order to delete items. Please note that this action is not as efficient as
the above two actions.
quit
This lets you quit without do cleaning.
help
