bash: use outside variables when reading multiple lines into ssh Use the ssh options -t or -T to force/disable a pseudo-tty, depending on your needs. That will at least take care of the error message. |

bash: use outside variables when reading multiple lines into ssh What's happening is that you're logging on to the remote server, running bash non-interactively, and that exits right away. Then the commands in the heredoc get executed. Simply remove "/bin/bash" from the ssh command and it will execute the heredoc remotely. |

Setting “say” alias for espeak on Ubuntu Linux Also, aliases do not use positional parameters. You would need to use a function: say() { espeak -s 120 2>/dev/null <<< "$*"; }. But @John has given you the correct answer. |

split array element with special character Is that the output of the Perl script that you now want to reformat? Or is that what you want to see and you have not shown what Perl outputs? I don't see any ~ characters there. |

Export system wide env variables at boot yes. Or you could wrap the client in a shell script that sources the profile. |

bash/sed/awk/etc remove every other newline A late comment: 1) always use a format specifier for printf in case the string has percent signs, 2) to avoid the duplicated last line, set $0 to "" -- awk '{printf "%s", $0; $0=""; getline; print " " $0}' |

linux + match only VALID IP from text file into other file In fact, can tighten up the one-liner: perl -MRegexp::Common=net -lne 'print for /(?<!\d)($RE{net}{IPv4})(?!\d)/' |

linux + match only VALID IP from text file into other file Use lookaround assertions to eliminate the false positives: /(?<!\d)($RE{net}{IPv4})(?!\d)/ |

linux + match only VALID IP from text file into other file If you use grep -oP you can use look-around constraints to limit the invalid first and last octets: grep -oP '(?<!\d)(1?\d?\d|2[0-4]\d|25[0-5])(\.(1?\d?\d|2[0-4]\d|25[0-5])){3}(?!\d)' |

Problems with bash variable expanding with single quotes @drcelus, in what context do single quotes appear? If it is in set -x output, don't worry about it: they appear just for your (visual) benefit, they don't affect the execution of the command. |

.bashrc: shopt: not found I find that's not always accurate (may depend on one's rc files). From bash, try /bin/sh -c 'echo $SHELL' -- for me that returns "/bin/bash" even though my /bin/sh is a symlink to dash. |

.bashrc: shopt: not found Agree with @womble. Even the error messages say sh. What does cat /proc/$$/cmdline show? |
