readarray

Read lines from stdin into an array. More information: https://www.gnu.org/software/bash/manual/bash.html#index-readarray.

• Interactively input lines into an array:

readarray {{array_name}}

• Read lines from a file and insert them in an array:

readarray < {{path/to/file.txt}} {{array_name}}

• Remove [t]railing deliminators (newline by default):

readarray < {{path/to/file.txt}} -t {{array_name}}

• Copy at most n lines:

readarray < {{path/to/file.txt}} -n {{n}} {{array_name}}

• [s]kip the first n lines:

readarray < {{path/to/file.txt}} -s {{n}} {{array_name}}

• Define a custom [d]elimiter:

readarray < {{path/to/file.txt}} -d {{delimiter}} {{array_name}}
