• Inline comments for bash?

  - by Lajos Nagy

  I'd like to be able to comment out a single flag in a one-line command. Bash only seems to have `from # till end-of-line' comments. I'm looking at tricks like: ls -l $([ ] && -F is turned off) -a /etc It's ugly, but better than nothing. Anybody has any better suggestions?

• Bash script, read values from stdin pipe

  - by gmatt

  I'm trying to get bash to process data from stdin that gets piped it, but no luck, what I mean is none of the following work: echo "hello world" | test=($(< /dev/stdin)); echo test=$test test= echo "hello world" | read test; echo test=$test test= echo "hello world" | test=`cat`; echo test=$test test= where I want the output to be test=hello world. Note I've tried putting "" quotes around "$test" that doesn't work either.

• bash completion for Subversion

  - by khmarbaise

  I've tried to load bash_completion in my bash (3.2.25), it does not work. No message etc. I've used the following in my .bashrc if [ -f ~/.bash_completion ]; then . ~/.bash_completion fi I also tried to use .bash_profile instead, but with the same result. So the problem is why does it not work? Any idea? Hints?

  When working with Bash, I can put the output of one command into another command like so: my_command `echo Test` would be the same thing as my_command Test (Obviously, this is just a non-practical example.) I'm just wondering if you can do the same thing in Batch.

• BASH Arithmetic Expressions

  - by Arko

  I had used several ways to do some simple integer arithmetic in BASH (3.2). But I can't figure out the best (preferred) way to do it. result=`expr 1 + 2` result=$(( 1 + 2 )) let "result = 1 + 2" What are the fundamental differences between those expressions? Is there other ways to do the same? Is the use of a tool like bc mandatory for floating point arithmetic? result=`echo "7/354" | bc`

• Command to escape a string in bash

  - by User1

  I need a bash command that will convert a string to something that is escaped. Here's an example: echo "hello\world"|escape|someprog Where the escape command makes "hello\world" into "hello\\world". Then, someprog can use "hello\world" as it expects. Of course, this is a simplified example of what I will really be doing.
