Day 1: 17x
Reason for stopping: Arm exhaustion
Status: My arms hurt like crazy. I can't even type this properly. I am wondering if this is a wise idea. OUCH. I am not entirely sure I have the right form. I need to check with my department-mate about this tomorrow.

NB: Hmm... can't tell if this journal format is working.

I memorized this speech back in the day.


Resounds in my head to this day, at the most inopportune moments.

(E:strip) has sort of changed for me in the past couple months as more of a personal referencing and note-taking environment. (e:Paul) told me that wildcard searching and grepping could be a likely feature in the near future, so I am pretty excited about how else I can push (e:strip)'s limits.

I started some experimentation with establishing habits through journalling a couple years back but that wasn't so very successful. My "goals" category is littered with decapitated angels of change. I think I murdered them all because I lacked the correct motivation. I think I have it now. The thing is I tried the urdhva dhanurasana just now and could not repeat the success at yoga class from last week. So frustrating! And I pretty much know why. I really really really would like some functional muscles on my arms. They are weak and a complete disgrace to the 13,550,471,400+ human arms on the planet. They have no muscle definition and look like they were grafted on me from an early 1700s graveyard-spare-bones-and-cadavers-department.

So push ups it is. At 10:13 PM everyday, as many push-ups as I can do in 5-10 minutes. (I can't do a "real" push-up yet so I am going to start with push-ups-on-my-knees.)

Of course, now how does (e:strip) come into it? I am not sure yet... maybe a post checking in on success or failure immediately after I finish the task? They say that if you keep it up for 21 days, a habit is established (personally, I think that is such tripe... but I could be wrong. I kind of want to be wrong on this one.) Who wants to be in my accountability peanut gallery and throw rocks? Or better still, does someone else have a 10:13 or even 10:31 goal they want to implement? Brush your teeth every night, perhaps?

A single push-up for me, a giant floss for you? It's project Armstrong!

See you around 10:30-ish.

This gem by The Kinks is SO (e:matthew). haha

She infuses something indescribably rustic and precise into the classic.

The already super-awesome Classic:

Another set of commands I need to burn into my brain:

Find all files in the current directory that contain blah in their file names

• ls |grep blah

Wildcards in grep: all files that start with a b and end in a g with ONLY one character in between

• grep b.g file

The asterisk * in a grep command stands for repetition. .* means "repeat any character any number of times"

• grep "b.*g" file

Escaping characters. Preceding backslashes either remove an implied special meaning from a character or add special meaning to a "non-special" character

• grep 'hello\.gif' file

An expression consisting of a character followed by an escaped question mark matches one or zero instances of that character.

• bugg\?y matches bugy , buggy but not bugggy

An expression surrounded by "escaped parentheses" is treated as a single character.

• Fred\(eric\)\? Smith matches Fred Smith or Frederic Smith

Match a selection of characters, use []

• [Hh]ello matches lines containing hello or Hello
• [A-Ca-k] is the same as [ABCabcdefghijk]
• [[:alpha:]] is the same as [a-zA-Z]
• [[:upper:]] is the same as [A-Z]
• [[:lower:]] is the same as [a-z]
• [[:digit:]] is the same as [0-9]
• [[:alnum:]] is the same as [0-9a-zA-Z]
• [[:space:]] matches any white space including tabs

The [] may be used to search for non-matches. This is done by putting a carat ^ as the first character inside the square brackets.

• grep "([^()]*)a"

matches (hello)a, (aksjdhaksj d ka)a But not
x=(y+2(x+1))a (I don't get this part, does it match (y+2(x+1))a?)

This matches phone numbers, possibly containing a dash or whitespace in the middle.

• grep "[[:digit:]]\{3\}[ -]\?[[:digit:]]\{4\}" file

The $ character matches the end of the line. The ^ character matches the beginning of the line.

• grep "^From.*mscharmi" /var/spool/mail/elflord
• grep "^[[:space:]]*hello[[:space:]]*$" file

The expression consisting of two expressions seperated by the or operator \| matches lines containing either of those two expressions.

• grep "I am a \(cat\|dog\)" matches lines containing the string "I am a cat" or the string "I am a dog"

The expression \n where n is a number, matches the contents of the n'th set of parentheses in the expression
"Mr \(dog\|cat\) came home to Mrs \1 and they went to visit Mr \(dog\|cat\) and Mrs \2 to discuss the meaning of life matches the respective dog/cat pairs

The following characters are considered special and need to be "escaped":
? \ . [ ] ^ $

A $ sign loses its meaning if characters follow it and the carat ^ loses its meaning if other characters precede it.

Square brackets behave a little differently. The rules for square brackets go as follows:

1. A closing square bracket loses its special meaning if placed first in a list. for example []12] matches ] , 1, or 2.
2. A dash - loses it's usual meaning inside lists if it is placed last.
3. A carat ^ loses it's special meaning if it is not placed first
4. Most special characters lose their meaning inside square brackets

• grep "$HOME" file searches file for the name of your home directory, while
• grep '$HOME' file searches for the string $HOME

Find with specific strings on filenames

• find . -name "*.jpg"
• find . -iname "*.jpg" #case insenstive version

Look for specific filetypes

• find . -type d #directories
• find . -type f #files
• find . -type l #links (wth?)
• find . -type s #sockets (wth?)

Find by size:

• find ~/Movies/ -size +1024M

Find by last modified time (last 1 day)

• find /etc/ -user root -mtime 1

Arguments
-atime: when the file was last accessed
-ctime: when the file's permissions were last changed
-mtime: when the file's data was last modified
-amin: when (in minutes) the file was last accessed
-cmin: when (in minutes) the file's permissions were last changed
-mmin: when (in minutes) the file's data was last modified

!
exclude everything that comes after this...

Collect files that are not owned by valid users and delete them

• find / -nouser -print0 | xargs -0 rm

Clean the images off of your *nix desktop

• find ~/Desktop -name "*.jpg" -o -name "*.gif" -o -name "*.png" -print0 | xargs -0 mv --target-directory ~/Pictures
• The -print0 option terminates results with a null character instead of the default newline, making it cleaner and less likely to balk in many cases

Correct the permissions on your web directory

• find /your/webdir/ -type d -print0 | xargs -0 chmod 755
• find /your/webdir -type f | xargs chmod 644

Show a list of files in /etc that have been modified since last month

• find /etc -mtime -30
