upg.sh my dump.txt to note.md
SYNOPSIS: upg.sh
- Upgrade your system and store stdout into a markdown file.
#!/bin/bash

# step 1: formatting.

Script breakdown: upg.sh
First, we declare bash as our shell with
#!/bin/bash. We could also use#!/bin/shfor a more portable script.I like to paste the name of the script we're working on into the script itself
# upg.sh.Setup a couple of variables to shorten the syntax.
FILENAME=sys-upgrade$(date +%m-%d-%Y).md
DIRECTORY="${HOME}/Documents/"
# step 1: formatting.- Build labels and a short breakdown of the update/upgrade commands used.
echo -e "# **System Upgrade:** $(date)\n" \ <-- formatting: label with date.
| tee -a ${DIRECTORY}${FILENAME} <-- path/to/file
echo -e "**Command:** \`sudo apt-get update; sudo apt-get upgrade --yes\`\n" \ <-- formatting: command label.
| tee -a ${DIRECTORY}${FILENAME} <-- path/to/file
echo -e "**Command Breakdown:**" \ <-- formatting: label.
| tee -a ${DIRECTORY}${FILENAME} <-- path/to/file
echo -e "- \`sudo\`, Admin Privilages." \ <-- formatting: label.
| tee -a ${DIRECTORY}${FILENAME} <-- path/to/file
echo -e "- \`apt-get\`, Package Manager." \ <-- formatting: label.
| tee -a ${DIRECTORY}${FILENAME} <-- path/to/file
echo -e "- \`update;\`, Package Manager's task; update the system software repositories." \ <-- formatting: label.
| tee -a ${DIRECTORY}${FILENAME} <-- path/to/file
echo -e "- \`sudo apt-get upgrade\`, Perform system upgrade with updated repositories." \ <-- formatting: label.
| tee -a ${DIRECTORY}${FILENAME} <-- path/to/file
echo -e "- \`--yes\`, Answers yes to the prompt." \ <-- formatting: label.
| tee -a ${DIRECTORY}${FILENAME} <-- path/to/file
# step 2: run commands with formatting.,- Setup labels and an area for the stdout to be store with markdown formatting.
- We place the time and date into the stdout area then run the commands.
echo -e "\n**Command std-output:**\n" \ <-- formatting: label.
| tee -a ${DIRECTORY}${FILENAME}
echo -e "\`\`\`" \ <-- formatting: markdown.
| tee -a ${DIRECTORY}${FILENAME}
echo $(date) \ <-- command: date.
| tee -a ${DIRECTORY}${FILENAME}
sudo apt-get update \ <-- command: update.
| tee -a ${DIRECTORY}${FILENAME}
echo -e "\n# System update completed.\n" \ <-- formatting: label.
| tee -a ${DIRECTORY}${FILENAME}
sudo apt-get upgrade --yes \ <-- command: upgrade with "--yes" option.
| tee -a ${DIRECTORY}${FILENAME}
echo -e "\n# System upgrade completed.\n" \ <-- formatting: label.
| tee -a ${DIRECTORY}${FILENAME}
echo -e "\`\`\`\n" \ <-- formatting: markdown.
| tee -a ${DIRECTORY}${FILENAME}
# step 3: additional details with more formatting.,- List the packages that were upgraded with details from system cache.
echo -e "**Upgraded Package Details:**\n" \ <-- formatting: label.
| tee -a ${DIRECTORY}${FILENAME}
echo -e "\`\`\`" \ <-- formatting: markdown.
| tee -a ${DIRECTORY}${FILENAME}
PKGLIST=$(sed -n "/The following packages will be upgraded:/,/^.. upgraded/p" ${DIRECTORY}${FILENAME} \ <--| variable with list of packages within it.
| sed '1d;$d' | xargs -n 1 | sed '/:i386$/d') \ <--| sed: filter the first and last lines then remove the :i386 duplicate packages.
PKGCACHE=$(echo -e "${PKGLIST}\n" \ <--| variable with massive apt-cache search results.
| xargs -n1 -I _ apt-cache search _) <--| xargs runs the PKGLIST (the _ is the value of PKGLIST) into the apt-cache search.
echo "${PKGCACHE}" > ${DIRECTORY}delete.txt <--| I had to put the PKGCACHE in a file. I couldn't get sed to filter a variable (yet).
echo "${PKGLIST}" \ <--| use that PKGLIST to create a few sed commands to filter the file called "delete.txt".
| xargs -n 1 -I _ echo "sed -n '/^_ /p'" "${DIRECTORY}delete.txt" \ ^--| xargs is used to create the sed commands.
| bash | tee -a ${DIRECTORY}${FILENAME}; <--| run the sed commands through bash then store them.
echo -e "\`\`\`" \
| tee -a ${DIRECTORY}${FILENAME}
rm -v ${DIRECTORY}delete.txt; <--| use rm to delete the file called "delete.txt" it has the apt-cache search results in it.
PKGLIST= <--| empty the variable. why? why not!
PKGCACHE= <--| empty the variable. why? why not!
# step 4: place EOF (end of file).,- Add EOF (END OF FILE) to the end of the file. If one is already there, -
- it's removed then replaced in the correct position.
sed -i '/EOF/d' ${DIRECTORY}${FILENAME} <--| search for EOF then remove it. we don't want multiple EOF if we run the script multiple times in the same day.
echo "EOF" >> ${DIRECTORY}${FILENAME} ^--| adds the EOF (End Of File) at the end of the file. I read it was a nice thing to do.
#EOF <--| Yep. it's there.
SYNOPSIS: note.sh "command" "filename"
- example: note.sh "ls -lhA" "basic-list"
- make markdown notes of your commands.
#!/bin/bash
# note.sh "command" "filename" no extentions.
# variables

# step 1: create file with formatting.
echo -e "# **Command:** \` $1 \`\n" \

echo -e "**Command Breakdown:**" \
| tee -a ${DIRECTORY}${FILENAME}
echo "$1" | tr " " '\n' \
| awk '{ print "- `" $0 "`, info." }' \
| tee -a ${DIRECTORY}${FILENAME}
# step 2: run command with more formatting.
echo -e "\n**Command std-output:**" \

echo $1 | bash \
| tee -a ${DIRECTORY}${FILENAME}
echo -e "\`\`\`" \
| tee -a ${DIRECTORY}${FILENAME}
echo -ne "\n${FILENAME} has been updated $(date)."
# step 3: insert EOF (End Of File).
sed -i '/EOF/d' ${DIRECTORY}${FILENAME}
echo EOF >> ${DIRECTORY}${FILENAME}

#!/bin/bash. We could also use#!/bin/shfor a more portable script.I like to paste the name of the script we're working on into the script itself
# upg.sh.Setup a couple of variables to shorten the syntax.
FILENAME=$2$(date +%m-%d-%Y).md <--| the "$2" is the second user input (file name) from the commandline.
DIRECTORY="${HOME}/Documents/"
# step 1: create file with formatting.- Build labels for Command Name with a short breakdown of the command(s) used.
- Note: the breakdown must be entered manually.
echo -e "# **Command:** \` $1 \`\n" \ <--| the "$1" is the first user input (the command) from the commandline.
| tee -a ${DIRECTORY}${FILENAME}
echo -e "**Command Breakdown:**" \
| tee -a ${DIRECTORY}${FILENAME}
echo "$1" | tr " " '\n' \ <--| This just breaks the command into parts then adds some markdown formatting for use to add -
| awk '{ print "- `" $0 "`, info." }' \ ^--| details to later. I just added the word info so you know to provide info about the command. -
| tee -a ${DIRECTORY}${FILENAME} ^--| the formatting gets a bit crazy if you use something like: awk {' print $1 $2 $3 '} path/to/file; each space becomes a newline with the markdown formatting.
# step 2: run command with more formatting.- Echo the Command into bash with markdown formatting for stdout.
echo -e "\n**Command std-output:**" \
| tee -a ${DIRECTORY}${FILENAME}
echo -e "\`\`\`\n$(date)" \
| tee -a ${DIRECTORY}${FILENAME}
echo $1 | bash \
| tee -a ${DIRECTORY}${FILENAME}
echo -e "\`\`\`" \
| tee -a ${DIRECTORY}${FILENAME}
echo -ne "\n${FILENAME} has been updated $(date)."
# step 3: insert EOF (End Of File).- Add EOF (END OF FILE) to the end of the file. If one is already there, -
- it's removed then replaced in the correct position.
sed -i '/EOF/d' ${DIRECTORY}${FILENAME}
echo EOF >> ${DIRECTORY}${FILENAME}
