"This Week" script: in bash, awk, or whatever.

Maybe me. Because his comment is under my post. But i'm fixed one bug and there is one more

I see.

Ah yes, bugs.
We amateur devs have quite the insect collection, don't we!

[nosystemdthanks]

musher: first i noticed that grep wouldnt apply if it was the 8th, then i noticed other code that fixed it.

even if i was right about the code in question, the code that fixed it meant that the author was aware of the issue and had a fix on another line, so pointing it out was moot.

[puppy_apprentice]

It seems that will works:

Code: Select all

echo "     " $(cal | head -n 1) ; echo "  " $(cal | head -n 2 | tail -1) ;  cal | tail -n +3 | grep -n "$(date +%d)" | tr ':' ' ' | echo "w"$(grep --color=always " $(date +%d) ")

Checked for eg. 8th:

Code: Select all

echo "     " $(cal | head -n 1) ; echo "  " $(cal | head -n 2 | tail -1) ;  cal | tail -n +3 | grep -n "8" | tr ':' ' ' | echo "w"$(grep --color=always " 8 ")

Arrghh. Not working. Look on the pic for 8th. I have to clean my glasses It sems that without sed/awk i won't colorize my output.


Maybe this (check this somebody before i start to be insane ):

Code: Select all

echo "    " $(cal | head -n 1) ; echo "w:"$(cal | head -n 2 | tail -1) ;  cal | tail -n +3 | grep -Ewn --color=always "$(date +%d)"
echo "    " $(cal | head -n 1) ; echo "w:"$(cal | head -n 2 | tail -1) ;  cal | tail -n +3 | grep -Ewn --color=always "8"
echo "    " $(cal | head -n 1) ; echo "w:"$(cal | head -n 2 | tail -1) ;  cal | tail -n +3 | grep -Ewn --color=always "18"

[musher0]

Hi Puppy_Apprentice.

Nope. You're not insane!!! Your line

Code: Select all

echo "    " $(cal | head -n 1) ; echo " " $(cal | head -n 2 | tail -1) ;  cal | tail -n +3 | grep -Ewn --color=always "$(date +%d)"

does not show the "w" abbreviation on my set-up, though.

As to my own kind of insanity... here is my 3rd iteration. Hopefully the
ANSI escape code magic provided by

Code: Select all

echo -e "\e[1A\e[C$Sem"

at line 49 will show on someone else's box. (Scrot included.)

Code: Select all

I don't have <nl> command in my Slacko 5.7 (devx not loaded) - picture 1

Ok, my last solutions (i think that i can't make them shorter without loose colors and don't use awk/sed) - picture 2

Code: Select all

#!/bin/sh

# version 1 (grep is last so print colors normally):
echo "    " $(cal | head -n 1) ; echo "w:"$(cal | head -n 2 | tail -1) ;  cal | tail -n +3 | grep -Ewn --color=always "$(date +%d)"

# version 2 (grep isn't last so color and number for week are extracted from line variable):
cal | head -n 2 ; line=$(cal | tail -n +3 | grep -Ewn --color=always "$(date +%d)") ; echo ${line:30} \(${line:0:12}\)

Thx musher0 for topic. I had fun and have idea for console pim - THE OSMO KILLER

[MochiMoppel]

Ok, my last solutions (i think that i can't make them shorter without loose colors and don't use awk/sed) - picture 2

Code: Select all

#!/bin/sh

# version 1 (grep is last so print colors normally):
echo "    " $(cal | head -n 1) ; echo "w:"$(cal | head -n 2 | tail -1) ;  cal | tail -n +3 | grep -Ewn --color=always "$(date +%d)"

# version 2 (grep isn't last so color and number for week are extracted from line variable):
cal | head -n 2 ; line=$(cal | tail -n +3 | grep -Ewn --color=always "$(date +%d)") ; echo ${line:30} \(${line:0:12}\)

Your scripts will not work for dates < 10
The command "$(date +%d)" will return zero padded numbers (e.g. 01) while cal returns the first day of the month as '1'. Your grep command will not find a match.

- You should force date to return unpadded numbers by adding a '-' after the % :"$(date +%-d)"
- You must surround the echoed expression in version 2 with doublequotes to prevent echo from stripping leading/trailing spaces (e.g. the first week of this month would be printed left aligned, with '1' showing as a Sunday ...)
- Removing 2 backslashes and 1 E option offsets the three added characters

Your 2nd version would look like this:

Code: Select all

cal | head -n 2; line=$(cal | tail -n +3 | grep -wn --color=always "$(date +%-d)"); echo "${line:30}  (${line:0:12})"

[fredx181]

The prize for the "bash script of the week" goes to...

musher0 (and everybody else ) Great thread !

Next week another, maybe "bash script of the month" ?

[puppy_apprentice]

Code: Select all

# Mochi adjustments with more colors
l=$(cal | tail -n +3 | grep -wn --color=always "$(date +%-d)"); echo "${l:0:6}"; cal | head -n 2; echo -e "${l:9:3}${l:30} (${l:0:12})\n"
l=$(cal | tail -n +3 | grep -wn --color=always "$(date +%-d)"); echo "${l:15:6}"; cal | head -n 2; echo -e "${l:24:3}${l:30} (${l:0:12})\n"

Learn from Mochi kids, he knows things

[rufwoof]

Thanks (generally). I've modified my console (terminal) on which I run tmux and the default window shows a tput based menu, alongside a current month cal that previously I'd set to be just cyan - but now that has the current day 'highlighted' in a different colour by using the concepts detailed in this thread.

Image is a actual android phone (somewhat wobbly) snap as OpenBSD by default for security reasons prevents software based snaps of the console.

ksh snippet for the date and time functions

Code: Select all

_show_date_time () {

    while : 
    do
	       tput sc
	       tput bold
               tput setaf 3
	       tput cup 11 5
	       echo `date +" %R %a %d %b"`
	       tput rc
	       sleep 15
    done &
    PIDofdatetime=$!

}

_show_cal () {
    
    tput bold
    tput setaf 6
    echo;echo;echo
    B=$(tput setaf 5;tput setab 7;tput rev;tput bold)
    U=$(tput sgr0;tput setaf 6;tput bold)
    DAY=$(date +%e | tr -d " ")
    cal | sed -E -e "s|(.*[^0-9])($DAY)([^0-9].*)|\1$B\2$U\3|" | sed 's/^/   /g'

I just can't get enough I'm starting to be addicted to bash.

Version with 2 random colors for headers:

Code: Select all

sn=$(echo -e "0\n15"); s=($sn); en=$(echo -e "9\n24"); e=($en); r=$((RANDOM%2)); l=$(cal | tail -n +3 | grep -wn --color=always "$(date +%-d)"); echo "${l:s[$r]:6}"; cal | head -n 2; echo -e "${l:e[$r]:3}${l:30} (${l:0:12})\n"

[musher0]

Hello, puppy_apprentice_"no_more"!

You lost me, there!
Please explain what you're doing, to us simple mortals?

Thanks.

[puppy_apprentice]

I think that you know all the bash magic like Mochi, but ok i will explain my tricks:

1)

Code: Select all

l=$(cal | tail -n +3 | grep -wn --color=always "$(date +%-d)")

this store in var l eg:

Code: Select all

X14X2Y1:Y218 19 20 21 22 23 24

where X1/X2 - starts/ends ANSI code for color green and Y1/Y2 starts/ends ANSI code for color light blue.

2)

Code: Select all

sn=$(echo -e "0\n15"); s=($sn); en=$(echo -e "9\n24"); e=($en); r=$((RANDOM%2));

looks better in that view:

Code: Select all

sn=$(echo -e "0\n15")
s=($sn)
en=$(echo -e "9\n24")
e=($en)
r=$((RANDOM%2));

make two arrays with colors coordinates in string stored in var l, s for starting coordinates and e - for ending coordinates:
for green: X1 = 0, X2 = 9
for l. blue: Y1 = 15, Y2 = 24

r store 0 or 1, so if we get 0 we get start/end X1/X2 coordinates for ANSI code for color green

3) that we can put there:

Code: Select all

echo "${l:s[$r]:6}"; cal | head -n 2; echo -e "${l:e[$r]:3}${l:30} (${l:0:12})\n"

[nosystemdthanks]

useful: https://explainshell.com/

but this example is too much for it.

[puppy_apprentice]

musher0 this code you can use in your scripts:

Code: Select all

#!/bin/sh
colors=$(echo -e "34\n35\n36\n37"); colmatrix=($colors); r=$((RANDOM%4)); echo -e "\e[${colmatrix[$r]}m Hello World! \e[0m"

[musher0]

@puppy_apprentice:

Your modesty is quite to be commended. But judging by your recent output,
I'd say that you're well on your way of surpassing at least this supposed
"Bash magic" master... (I.e. me.)

That's fine, and please go for it! I have serious reservations about the
traditional concept of "competition", but I'm all for "emulation".

My best wishes to you in this!

BFN.

[puppy_apprentice]

I was thinking about your ThisWeek.sh script in wich you use ANSI codes.

Ok. I have some experience with other programming languages but i'm not fluent in any.

I think that for example i won't write this kind of sed game:

https://aurelio.net/projects/sedsokoban/

Have a nice day/evening all.

[musher0]

Thanks for the feedback, puppy_apprentice.

~~~~~~~~~~~
@all:

If anyone is interested, I have made available the latest version of
coreutils, version 8-30, for PuppyLinux, here.

To anyone wondering: the link with this thread is that the GNU coreutilis
contain, among many others, three utilities used in various scripts in this
thread: cal (the full version), date and nl.

BFN.

[musher0]

Hello all.

In lieu of < nl > to number lines, one can use < cat -n >:

Code: Select all

>echo;cal | grep -v [[:alpha:]] | cat -n | grep --color=always "$(date '+%d')"

Also possible for this is the use of < grep -n >, as mentioned somewhere
above by puppy_apprentice IIRC:

Code: Select all

echo;cal | grep -v [[:alpha:]] | grep -n --color=always "$(date '+%d')" | tr ":" "\t";echo -e "\e[1A\e[1Cth wk:"

This is completed by a replacement, through < tr >, of the colon by a tab,
and then we insert for information the string "th wk:" between the week
number and the line of dates, through a couple of ANSI escape codes.

We can decorate it like so:

Code: Select all

echo;echo -e "\t      \e[33m\e[4m`date '+%b %Y'`\e[0m";cal | grep -v [[:alpha:]] | grep -n --color=always "$(date '+%d')" | tr ":" "\t";echo -e "\e[1A\e[1Cth wk:";echo -e "\t\e[33m`cal | grep -v [[:digit:]]`\e[0m"

Scrot attached.

BFN.
