In bash I'm trying to exit with "|", "/", "-" or "\" but it complains I need to exit with an integer. I don't know how to convert it to integer and in the calling program I'll be stuck trying to convert the integer result back to character. Any clues anyone??? thanks.
#!/bin/bash
# return "|", "/", "-", "\" sequentially with each call to this script.
# Use /tmp/last-text-spinner to store last used
FILE="/tmp/last-text-spinner"
if ! [ -f $FILE ]; then
echo "|" > $FILE
exit 124 # ASCII equivalent for "|" bash doesn't allow character return codes
fi
LAST=$(cat $FILE) # read last character used
if [[ $LAST=="|" ]]; then
echo "/" > $FILE
exit 47 # ASCII equivalent
elif [[ $LAST=="/" ]]; then
echo "-" > $FILE
exit 45 # ASCII
elif [[ $LAST=="-" ]]; then
I've done it all the way through... error is fixed. something wrong with the code though as it loops through "|" then "/" and gets stuck there forever.
#!/bin/bash
# return '|', '/', '-', '\' sequentially with each call to this script.
# Use /tmp/last-text-spinner to store last used
FILE="/tmp/last-text-spinner"
if ! [ -f $FILE ]; then
echo '|' > $FILE
exit 124 # ASCII equivalent for '|' bash doesn't allow character return codes
fi
LAST=$(cat $FILE) # read last character used
if [[ $LAST=='|' ]]; then
echo '/' > $FILE
exit 47 # ASCII equivalent
elif [[ $LAST=='/' ]]; then
echo "-" > $FILE
exit 45 # ASCII
elif [[ $LAST=='-' ]]; then
#!/bin/bash
# Use /tmp/last-text-spinner to store last used
FILE="/tmp/last-text-spinner"
if ! [ -f $FILE ]; then
echo '|' > $FILE
exit 124 # ASCII equivalent for '|' bash doesn't allow character return codes
fi
LAST=$(cat "$FILE") # read last character used
if [[ "$LAST" == '|' ]]; then
echo 'I see a pipe!'
echo '/' > $FILE
exit 47 # ASCII equivalent
elif [[ "$LAST" == '/' ]]; then
echo "-" > $FILE
exit 45 # ASCII
elif [[ "$LAST" == '-' ]]; then
echo '\' > $FILE # must use single quote, when double quoted BASH reinterprets
oh you can remove that echo from the first if statement. That was a debugging echo :P
I just edited to follow some bash best practices and that seemed to fix it (spaces between comparisons, quote your variables during comparisons)
@WinEunuuchs2Unix So, for whatever reason, bash was matching $LAST to any string when there was no space between the operands and the ==. Frankly I'm not sure why. But bash is weird.
That'd probably be a question for @Serg or @terdon --^
@WinEunuuchs2Unix @WinEunuuchs2Unix without looking too much into it, I'll say that echo '|' > $FILE adds newline to the file, and that's what is supposed to be in LAST=$(cat "$FILE") as well.
I added a comment to the code, but not as extravegant as yours. Plus replaced "-" with "─" (line draw character) and now it looks like this:
elif [[ $LAST == '/' ]]; then # NOTE: you must have spaces around " == " else code breaks
echo '─' > $FILE
exit 9472 # ASCII
You know this text spinning pizza will end up in systray / application indicator from bash which you commented on in May 16, 2016 question that it might be possible.
@AndroidDev Good point... besides I should probably keep this system intact as a backup and buy another laptop in a year or two with double / triple power of everything including USB 3.1 or thunderbolt, etc.
Afterall I don't really need more RAM.
I just like buying new laptop enhancements as women like buying new shoes.
I've seen animated GIF images of screen casts (like the one below) promoted a few times on this site as a way to improve answers.
What toolchain is being used to create these? Is there a program that does this automagically, or are people taking screencasts, converting them into a series of st...
@Seth No and I probably won't. CM on my Nexus 7 kept dropping and auto re-mounting my usb. It ended up wiping out a huge number of dvd's I had copied with handbrake. The problem went away when i restored the original nexus rom.
@Seth Shouldn't your answer be revised to say that it's no longer in development after 2 years and 4 months? Or maybe confirm it's still in development?

It was the equivalent of a Mach 1.6 ejection at 40,000 feet, a jolt in excess of that experienced by a driver who crashes into a red brick wall at over 120 miles per hour. Only it had lasted perhaps nine times longer. And it had burst nearly every capillary in Stapp's eyeballs.
@JacobVlijm Hi, I have one query for you. Is there a way I can seperate emails in one file and URLs in another file using python? I have file that contains mixture of emails and URLS (with or with http,www). Is it possible to do?
@JacobVlijm Great. Also I forgot to mention that there might be some data that is not UTF-8 for and the lines in which the emails or URL are , they might have other characters. see the one I found was like this: (fbst=yht) [email protected]. So I need to be careful while doing any programing
@JacobVlijm and also the same domain problem. Do not need gmail, rediffmail, etc
@JafferWilson non-unicode can be left out, like in the answer. In you example above the (other) string to be ignored is space- separated from the email. That makes it easy to ignore. Filtering at the same time is never a problem.
@JafferWilson only the one I asked in the comment. I think in general mentioning a language (python) is risky, since it easily can be named purely programming. Better ask the question solution- focussed instead of language focussed.
@muru I know the principle is there, but I think I would rather this got an answer than closed - it's not exactly the same since they only want part of the structure (although, what's with the suspicious backslashes?) askubuntu.com/review/close/677035
Anybody here who knows a thing or two about smartphones?
I'm considering to buy a ZTE Blade A510, because they offer that for a hilariously cheap price here currently. gsm-specs.com/zte-blade-a510 Any thoughts?
Update:
I think the issue is that GRUB is taking a long time to load the kernel image.
Update 2
I was able to confirm that it is a GRUB issue by setting the background color of GRUB to green by using the command line accessed by pressing C when in GRUB.
When I hit enter, I get a blank green...
Right. and the got big MS funding to save them, but the community side wasn't going to survive that since everything would then change. In any case, the community will try to continue as Lineage OS; but I don't expect that to continue. Watch for them to kill that too or merge with the Sailfish people.
@JacobVlijm Actually I use Sublime 3 but learning Angular JS so I was recommended to use brackets for that as It give live preview etc etc etc So Want some opinions Whether to use or not :)
No but JOHN WICK original movie was great! (If I'm thinking of the right one).
@Seth I got your silentcast installed with minor chrome problem of not displaying .png images in README.md. Plus I can't record only systray area. It does entire window with no cropping?.
@Hizqeel No, I'm not ... but that is one good example why I'm doing what I'm doing here ... making unbootable systems boot into a "bright shining" and properly working desktop for the users ... what makes them happy and gives me some kind of satisfaction ! :)
@cl-netbox Hi CL :) Everything is wonderful! Minus 30 cloudy snowy weather is gone. Sky is blue. Sun is Bright. Heading to freezing (zero / 32) and wrote bash script to output text spinning running-pizza to ubuntu systray :)
@cl-netbox Canadians should be used to cold winters for sure. Immigrants might find it hard. I'm not a fanatic for the Edmonton Oilers... I have a San Jose Sharks baseball cap though because I like the logo only.
@jokerdino never been interested in Cricket either, so can't tell if it's OK or not.
Can I disable Ctrl+Shift+C in chrome somehow ? I'm so used to using that shortcut in terminal, that I do it automatically without thinking in chrome too, and that opens the javascript console or whatever that is
@cl-netbox yeah, alright! Just coding a bit, trying to get some of my codes a bit more C std compliant (which is as bigger a challenge then one can imagine)
@Seth Thanks for transparent window option Seth. I'll try that when I get back from the mall. The Google Chrome not being able to open .png files isn't your problem that's mine. I added one image viewer extension already but that didn't help. Your link to chrome extension for markup language support was very helpful in your documentation. I'm very impressed with your work!
@WinEunuuchs2Unix whoa, I didn't write the app (although I've helped with it at various times), I just packaged it all up into a PPA so it was easy to install :)
