I want to add text to a file using shell-scripts. The solution I know is if you want to insert your text into a newline (appending):
echo "mytext" >> myfile.txt what I want to have a continuous text at the end of process.
for ((I=0; I <72 ; I++)) do echo "mytext$I, " >> myfile.txt ????? done I want something like:
mytext0, mytext1, mytext2, mytext3, ...., mytext71 but instead I get:
mytext0, mytext1, .... mytext71 In bash (and also shell which support brace expansion), you can do:
printf '%s\n' "$(printf 'mytext%s\n\n' {1..71})" | paste -sd', ' - >out In POSIX shell:
printf '%s\n' "$( n=1 while [ "$n" -le 71 ]; do printf 'mytext%s\n\n' "$n" n=$((n+1)) done )" | paste -sd', ' - >out You just need to make sure you don't append a newline to the end of the output: just replace echo with either echo -n or printf. I'd recommend the latter as it's more portable.
echooutputs a newline each pass of the loop. do wantecho -n?
