At—At, Batch—Execute Commands at a Later Time
at—at, batch—execute commands at a later time at [–csm] [–f script] [–qqueue] time [date] [+ increment] at –l [ job...] at –r job... batch at and batch read commands from standard input to be executed at a later time. at allows you to specify when the commands should be executed, while jobs queued with batch will execute when system load level permits. Executes commands read from stdin or a file at some later time. Unless redirected, the output is mailed to the user. Example A.1 1 at 6:30am Dec 12 < program 2 at noon tomorrow < program 3 at 1945 pm August 9 < program 4 at now + 3 hours < program 5 at 8:30am Jan 4 < program 6 at -r 83883555320.a EXPLANATION 1. At 6:30 in the morning on December 12th, start the job. 2. At noon tomorrow start the job. 3. At 7:45 in the evening on August 9th, start the job. 4. In three hours start the job. 5. At 8:30 in the morning of January 4th, start the job. 6. Removes previously scheduled job 83883555320.a. awk—pattern scanning and processing language awk [ –fprogram–file ] [ –Fc ] [ prog ] [ parameters ] [ filename...] awk scans each input filename for lines that match any of a set of patterns specified in prog. Example A.2 1 awk '{print $1, $2}' file 2 awk '/John/{print $3, $4}' file 3 awk -F: '{print $3}' /etc/passwd 4 date | awk '{print $6}' EXPLANATION 1. Prints the first two fields of file where fields are separated by whitespace. 2. Prints fields 3 and 4 if the pattern John is found. -

DC Console Using DC Console Application Design Software
DC Console Using DC Console Application Design Software DC Console is easy-to-use, application design software developed specifically to work in conjunction with AML’s DC Suite. Create. Distribute. Collect. Every LDX10 handheld computer comes with DC Suite, which includes seven (7) pre-developed applications for common data collection tasks. Now LDX10 users can use DC Console to modify these applications, or create their own from scratch. AML 800.648.4452 Made in USA www.amltd.com Introduction This document briefly covers how to use DC Console and the features and settings. Be sure to read this document in its entirety before attempting to use AML’s DC Console with a DC Suite compatible device. What is the difference between an “App” and a “Suite”? “Apps” are single applications running on the device used to collect and store data. In most cases, multiple apps would be utilized to handle various operations. For example, the ‘Item_Quantity’ app is one of the most widely used apps and the most direct means to take a basic inventory count, it produces a data file showing what items are in stock, the relative quantities, and requires minimal input from the mobile worker(s). Other operations will require additional input, for example, if you also need to know the specific location for each item in inventory, the ‘Item_Lot_Quantity’ app would be a better fit. Apps can be used in a variety of ways and provide the LDX10 the flexibility to handle virtually any data collection operation. “Suite” files are simply collections of individual apps. Suite files allow you to easily manage and edit multiple apps from within a single ‘store-house’ file and provide an effortless means for device deployment. -

101 Useful Linux Commands - Haydenjames.Io
101 Useful Linux Commands - haydenjames.io Some of these commands require elevated permissions (sudo) to run. Enjoy! 1. Execute the previous command used: !! 2. Execute a previous command starting with a specific letter. Example: !s 3. Short way to copy or backup a file before you edit it. For example, copy nginx.conf cp nginx.conf{,.bak} 4. Toggle between current directory and last directory cd - 5. Move to parent (higher level) directory. Note the space! cd .. 6. Go to home directory cd ~ 7. Go to home directory cd $HOME 8. Go to home directory (when used alone) cd 9. Set permissions to 755. Corresponds to these permissions: (-rwx-r-x-r-x), arranged in this sequence: (owner-group-other) chmod 755 <filename> 10. Add execute permission to all users. chmod a+x <filename> 11. Changes ownership of a file or directory to . chown <username> 12. Make a backup copy of a file (named file.backup) cp <file> <file>.backup 13. Copy file1, use it to create file2 cp <file1> <file2> 14. Copy directory1 and all its contents (recursively) into directory2 cp -r <directory1> <directory2>/ 15. Display date date 16. Zero the sdb drive. You may want to use GParted to format the drive afterward. You need elevated permissions to run this (sudo). dd if=/dev/zero of=/dev/sdb 17. Display disk space usage df -h 18. Take detailed messages from OS and input to text file dmesg>dmesg.txt 19. Display a LOT of system information. I usually pipe output to less. You need elevated permissions to run this (sudo). -

General Education and Liberal Studies Course List
GELS 2020–2021 General Education/Liberal Studies/Minnesota Transfer Curriculum 2020–2021 Course List This course list is current as of March 25, 2021. For the most current information view the Current GELS/MnTC list on the Class Schedule page at www.metrostate.edu. This is the official list of Metropolitan State University courses that meet the General Education and Liberal Studies (GELS) requirements for all undergraduate students admitted to the university. To meet the university’s General Education and Liberal Studies (GELS) requirements, students must complete each of the 10 goal areas of the Minnesota Transfer Curriculum (MnTC) and complete 48 unduplicated credits. Eight (8) of the 48 credits must be upper division (300-level or higher) to fulfill the university’s Liberal Studies requirement. Each course title is followed by a number in parenthesis (4). This number indicates the number of credits for that course. Course titles followed by more than one number, such as (2-4), indicate a variable-credit course. Superscript Number: • Superscript number (10) indicates that a course meets more than one goal area requirement. For example, NSCI 20410 listed under Goal 3 meets Goals 3 and 10. Although the credits count only once, the course satisfies the two goal area requirements. • Separated by a comma (3,LS) indicates that a course will meet both areas indicated. • Separated by a forward slash (7/8) indicates that a course will meet one or the other goal area but not both. Superscript LS (LS): • Indicates that a course will meet the Liberal Studies requirement. Asterisk (*): • Indicates that a course can be used to meet goal area requirements, but cannot be used as General Education or Liberal Studies Electives. -
