Hello! Please ensure this PR only contains files for the shell tools exercises.
Please create another PR for the number systems exercise. Creating a separate branch for this will make things easier :)

Hi, good work on this sprint. There are a few different tasks you need to have another look at, I've left some pointer comments on them
| set -euo pipefail | ||
|
|

| # TODO: Write a command to output just the names of each player in London along with the score from their last attempt. | ||
| awk '$2 =="London" {print $1,$5}' scores-table.txt |

Will this still work if the player makes more than a few attempts?
| # TODO: Write a command to output the contents of all of the files in the helper-files directory to the terminal. | ||
| # We also want to see the line numbers in the output, but we want line numbers not to reset at the start of each file. | ||
| cd helper-files | ||
| cat helper-1.txt helper-2.txt helper-3.txt | cat -n |

Do you know how to make cat output and number multiple files in a single command?
| set -euo pipefail | ||
|
|
||
| # TODO: Write a command to output the number of lines in dialogue.txt that contain the word Doctor (regardless of case). | ||
| grep -i "Doctor" dialogue.txt | wc -l |

Can you complete this task only using grep in a single command?
| set -euo pipefail | ||
|
|
||
| # TODO: Write a command to output every line in dialogue.txt that does not contain the word "Hello" (regardless of case). | ||
| grep -v "Hello" dialouge.txt |

The task is also asking about case insensitivity here - can you update your solution for that?
| set -euo pipefail | ||
|
|
||
| # TODO: Write a command to output the name of every `.txt` file in this directory which contains a line of dialogue said by the Doctor. | ||
| grep "^Doctor" *.txt |

Can you build a single grep command that only shows the filename in the output?
|
|
||
| # TODO: Write a command which does the same as above, but sorted in the opposite order (oldest first). | ||
| cd child-directory | ||
| ls -1t | tail -r |

On my system tail -r does not seem to be a valid command. Can you complete this only using a single ls command?
| set -euo pipefail | ||
|
|
||
| # TODO: Write a command to output input.txt removing any line which contains a number. | ||
| sed '/^[0-9] [[:space]]/d' input.txt |
There was a problem hiding this comment.
Is it necessary for your regexp to include the [[:space]] test?
|
|
||
|
|
||
| # TODO: Write a command to output input.txt with one change: | ||
| sed 's/^\([0-9][0-9]*\) \(.*\)/\2 \1/' input.txt |

Do you need two number groups in your regexp here?
