find and delete files smaller than specific size

Probably neither faster nor better than -delete in find. It's just that I generally dislike teaching find builtin actions.

Compares two source directories, one original and one post configure and deletes the differences in the source folder

Good for when your working on building a clean source install for RPM packaging or what have you. After testing, run this command to compare the original extracted source to your working source directory and it will remove the differences that are created when running './configure' and 'make'.

Find and replace text within all files within a directory

find . = will set up your recursive search. You can narrow your search to certain file by adding -name "*.ext" or limit buy using the same but add prune like -name "*.ext" -prune xargs =sets it up like a command line for each file find finds and will invoke the next command which is perl. perl = invoke perl -p sets up a while loop -i in place and the .bak will create a backup file like filename.ext.bak -e execute the following.... 's/ / /;' your basic substitute and replace.

Find Duplicate Files (based on size first, then MD5 hash)

This is a modified version of the OP, wrapped into a bash function. This version handles newlines and other whitespace correctly, the original has problems with the thankfully rare case of newlines in the file names. It also allows checking an arbitrary number of directories against each other, which is nice when the directories that you think might have duplicates don't have a convenient common ancestor directory.

How to find all open files by a process in Solaris 10

Executing pfiles will return a list of all descriptors utilized by the process We are interested in the S_IFREG entries since they are pointing usually to files In the line, there is the inode number of the file which we use in order to find the filename. The only bad thing is that in order not to search from / you have to suspect where could possibly be the file. Improvements more than welcome. lsof was not available in my case Show Sample Output

Find stock debian package config files that have been modified since installation

This functionality seems to be missing from commands like dpkg. Ideally, I want to duplicate the behavior of rpm --verify, but it seems difficult to do this in one relatively short command pipeline. Show Sample Output

Ensure path permissions from '.' prior to root

`pwd` returns the current path `grep -o` prints each slash on new line perl generates the paths sequence: './.', './../.', ... `readlink` canonicalizes paths (it makes the things more transparent) `xargs -tn1` applies chmod for each of them. Each command applied is getting printed to STDERR. Show Sample Output

Get AWS temporary credentials ready to export based on a MFA virtual appliance

You might want to secure your AWS operations requiring to use a MFA token. But then to use API or tools, you need to pass credentials generated with a MFA token. This commands asks you for the MFA code and retrieves these credentials using AWS Cli. To print the exports, you can use: `awk '{ print "export AWS_ACCESS_KEY_ID=\"" $1 "\"\n" "export AWS_SECRET_ACCESS_KEY=\"" $2 "\"\n" "export AWS_SESSION_TOKEN=\"" $3 "\"" }'` You must adapt the command line to include: * $MFA_IDis ARN of the virtual MFA or serial number of the physical one * TTL for the credentials

Create a system overview dashboard on F12 key

Command binds a set of commands to the F12 key. Feel free to alter the dashboard according to your own needs. How to find the key codes? Type $ read Then press the desired key (example: F5) $ ^[[15~ Try $ bind '"\e[15~"':"\"ssh su@ip-address\C-m""" or $ bind '"\e[16~"':"\"apachectl -k restart\C-m"""

Which files/dirs waste my disk space

I added -S to du so that you don't include /foo/bar/baz.iso in /foo, and change sorts -n to -h so that it can properly sort the human readable sizes.

Display EPOCH time in human readable format using AWK.

Count the total amount of hours of your music collection

First the find command finds all files in your current directory (.). This is piped to xargs to be able to run the next shell pipeline in parallel. The xargs -P argument specifies how many processes you want to run in parallel, you can set this higher than your core count as the duration reading is mainly IO bound. The -print0 and -0 arguments of find and xargs respectively are used to easily handle files with spaces or other special characters. A subshell is executed by xargs to have a shell pipeline for each file that is found by find. This pipeline extracts the duration and converts it to a format easily parsed by awk. ffmpeg reads the file and prints a lot of information about it, grep extracts the duration line. cut and sed cut out the time information, and tr converts the last . to a : to make it easier to split by awk. awk is a specialized programming language for use in shell scripts. Here we use it to split the time elements in 4 variables and add them up.

See The MAN page for the last command

This works in bash. The "!!:0" limits the argument to man to be only the first word of the last command. "!!:1" would be the second, etc.

Monitor a file with tail with timestamps added

Should be a bit more portable since echo -e/n and date's -Ins are not.
